• Wonder if they want to acquire them in order to resell? That would be my only guess. Would it be possible to put a disclaimer that you will only send giveaway listings to members with activity or x amount of reputation? I’m sure there has to be a way to make sure it’s more legit.

• It is of utmost importance to acknowledge that when you put up a listing you are in absolutely no way required to give it to anybody that asks you.
  It is not a promise to sell to whoever requests a bra. Even if it's a sale!

  The goal would be that you choose to give the bra to the best new home it could have.

  You are always encouraged to indicate brand new accounts that you do not want to give them your free bra because you don't know if the bra would work for them.

  You could make it explicit in your listing description that you prefer users with certain minimum reputation or under personal evaluation, whatever your boob tells you is best.

  Additionally, if you find a message suspicious, you can take two ways. One is to reply and try to ask more about this person. It could be a legitimate user in need that saw the opportunity and signed up just to try it. That's all great, you can do a bit of detective work in the PMs trying to help them.

  Otherwise, don't hesitate to click the "Report as creep" option when your fur stands on end. 99.99% of the times those feelings have been correct from previous reports.

  Ultimately, remember you can block them https://www.bratabase.com/profile/update/block/ although remember that this does not solve the bigger problem of someone annoying everybody. This is a selfish action that only solves it for you individually. Negative situations should be addressed for everybody and not one by one.

• I highly recommend cacique if you haven't already.

• Have you looked into Aviana? I haven't done wirefree/softcup in over 10 years but when I did, Aviana had an interesting selection.

• I’m with you on this! Ugh! It seems to me users should have to log in at least once a month to keep their listings active.

• @faeriequeene YES! I agree wholeheartedly.

• What do you mean?

• @wilderness1 usually when I look at someones listings, it'll give me an option to view the full listing profile. Then the site will give me a whole bunch of charts about how they add dheir bras and whatnot.

• I'm not sure why, but you could try to search using the reference size, or 34:13

• Letter sizing isn’t consistent across different brands. When you search for J the system doesn’t know if you mean an index 10 J (GG in standard UK sizing) or an index 13 J (what it sounds like you actually want), so it just displays results for both. You can make searches more precise if you search by index sizes, so for UK 34J you would search 34:13 and it will bring up all equivalent sizes in all sizing systems. Hope that makes sense lol

• 1) It's always a good idea to use different passwords on all sites.
  But 2) There hasn't been a data breach on the site (at least that I'm aware of)

  The effect of getting logged out is a side effect of how sessions are coded on the site. They aren't too persistent and when I restart the server or make changes some sessions can be lost. I never thought of it as a huge deal having to re-log in. So I never really worried about that.

  About then notification from Google I'm not sure how that came to happen.

  I wish they came to ask here or to me before going to another site and claiming that such thing happened without more information :(

• To add another clarification. The way passwords are stored here on the site is using a "One way hash", which means that even if someone went to the database it would be impossible to obtain your passwords. So your password could not be revealed, it is impossible to know.

• Jj You are amazing and you have attracted a supportive base for all of us bra wearers. Thank you!

• This site is really great. I agree. There are definitely the odd weirdos that surface but protective measures are in place and, at the end of the day, they don’t last long. There’s been some big drama in the past but that’s been gone for a while now. I was in your position myself once so it’s only natural that I should pay it forward with the same kindness that was extended to me in my tough times.

• I find that Agent Provocateur is too expensive with inconsistent sizing and quality with a poor range of sizes. Hopefully, with good measurements of your bra, you should get some interest.

• I’ve had luck listing bras on eBay when they don’t sell here. Limited size range could be the problem on Bratabase, but with the wider audience of eBay that shouldn’t be an issue.

• I also don't understand recommendations. I wear 28 bands, and even though some are a bit too tight, most of them are fine. But bratabase recommends 30 and 32 bands :\
  Edit: Well, to be fair, I went and checked the ribcage measurements of people who wore 28 bands, and they are all smaller than me. So, apparently I'm the outlier.

• Welp, I think I'm the adult in charge of answering this. This may get a bit long.

  To be honest, it is very hard even for me to predict what the algorithm will throw out. One critical difference is that unlike everything else online, this algorithm doesn't obtain the results from an arithmetic formula. This will match ranges of your measurements to the ranges of all the other measurements of what's on the database. So it has the fatal flaw of learning from what people enter here.

  The way that the final result is obtained is by aggregating together the results of a bunch of "channels", each channel will implement a different algorithm on different set of measurements and find its own results. Then we put all these results together each with a confidence value and sort the first batch.
  There are also what I call "anti channels" which are results that should be excluded from the final recommendations, and here is where there may be need to improvement based on what you describe. The antichannels work similarly, there's a few of them, each with different algorithm and get aggregated with a confidence level.

  Here's a quick overview of the channels:
  https://www.bratabase.com/help/recommendations/

  There are a couple of other corrective charts where the results get contrasted with, some "global measurements per size" matrices that get updated with all the measurements as well.

  Something very backwards about this approach that's been bugging me the last couple of years is that, not all channels are always enabled. Each gets activated only if the user has provided enough data for this channel's algorithm to work (must have set fit on one bra, or must have indicated that at least one bra doesn't fit, must have entered such and such measurements on at least one bra and so on). So when more data is added, more channels are enabled, this means that the final confidence level is divided by a bigger denominator (number of active channels) making the cut thresholds much more sensible. As if there are less channels enabled, the thresholds are bigger and you may get even more results. So adding more data could pay off by giving less results (because it can be more accurate). It is a similar story to when less people vote and the bad candidates get stronger results.

  Overall, I think the general approach is very worth it, but a bunch of things need to be tuned and there are a few dozen of knobs in there, and some more to be added, for example band comfort and what each may accept as tight or loose.

  When you look at your results page, hovering on each result will show a small flap indicating the confidence level from which channel got it to be included, this is a hint if you think something is wrong, it is possible to use this to investigate a bit further, usually the biggest offender for false positives is "Based on profile measurements", this means that someone else with similar measurements indicates the bra fits. And when only one person said this, the signal gets confused with being stronger. Adding a minimum of input to normalize the signal ends up excluding too much of the database since we'd need to have at least that many minimun of users that reported that a particular bra model and size fit, and it is only a handful of such combination that have a high enough number of entries, which kills the discovery factor.

  Speaking of discovery, sometimes I feel that people would be much more satisfied if the results included less information and just do like every other calculator out there and only tell you "30F" and don't try to indicate which specific models. I think that this is the biggest cause of this engine having such bad fame, it tries more and gets judged differently, saying "30F" it claimed so little that it could not be judged if any bra in 30F doesn't fit. But trying to be more accurate it is much more falsifiable/verifiable.

  Another aspect of this more precise judgement ability, is that for many users with good data, the results will not be surprising, so when things go well, they are not worthy of raising any eyebrows, but when you suddenly get a 32A in the list, then the full results get judged because of the bad sheep. The expectations get much higher and errors are much less forgiven.

  Thanks for coming to my Ted talk :)
  Thanks for adding your data to the site :)

• From what I understand, you add it anyway. Discontinued or not.

• I THINK you should be able to add it as a discontinued bra if it is listed there as the same model name and number. Check the tag for the model number.

  Jj can you confirm?

• Did you recently update your measurements? Do you have any bras that currently fit?

• I'm going to have a look at this. It's unusual that they're totally empty. At least find an explanation on why they're empty.

Cross posting listings

I had someone msg me and ask if it's OK to post bras for sale in multiple places. And yes it is totally fine, nobody owns the Internet to forbid you not to.

But I want to show some benefits of listing on Bratabase:

https://www.bratabase.com/my/listings/export/text/

If you go to that link, you can get an automatic piece of text with ... all your listings and pictures ready to share elsewhere, just copy and paste. This way you don't need to reupload elsewhere.

And the side benefit is that you may show Bratabase to other people, so when they come they may start adding their data and in an ideal world you can do the bra transfer over here. With your Bratabase listing you can keep track of all your sales/swaps.

• Yes, because even when the manufacturer doesn't make them they can still be around in the market (eBay, stock in many stores physical and online, Bratabase listings, selling your very own bra to someone else).

  Another case could be a relaunch with a new model name, but it's really the same cut bra, if we link it here we can benefit from older data.

  Also works as a standard measurement for brand/size data. So we can have info of what Asos' bras in 32E are in general.

  If there are cases to be argue against useless data is for brands that make products with irreproducible codes/models. Where it is impossible to buy the same product twice because you cannot run into it again ever. Some brands have a horrible product naming/coding scheme that makes it impossible to tell someone exactly which bra you have, then that data cannot really be aggregated with another bra. There are very few brands that do this.

  Also, this site grows as a database, there is lot of historic data and bra references that all other bra stores and sites have removed from their sites. So we are the last bastion with such information. All other sites will remove links to products once they aren't on sale and don't give them profit, but we hold long lived extensive data.

  About your Asos bra, you could just add it by creating the new model with the tag number of adding it as unknown even. At some point we may come and look at your pics and find the right model and fix your entry. This happens a LOT very often thanks to the uploaded pics, it's a common case with Asos with lots of rotating models.

• Yes it does. For all the reasons above. Discontinued models continue to circulate and any information is valuable.

• Hey! I'm a 26FF, so I hope I can give some helpful advice and recommendations. First of all, there aren't any brands that make a US 26G, so just use 26F or 55HH when searching for bras. Secondly, there aren't many brands out there that make 26 bands, so it may be easier for you to nail down your size in the first place by ordering your sister size of 28E. Cleo by Panache, Freya, Curvy Kate, and a handful of other brands carry bras in 28E, and those brands are available on Amazon, Bare Necessities, HerRoom, Figleaves, and a bunch of other sites. I would try to find bras that are eligible for free shipping and free returns while you're figuring things out in the beginning. There are also a few bras in 28E/55HH for sale here.
  Let me know if you need any more help! I'm here for you!

• sherrach898 hi thank you so much!! I do have a couple other brands in size 28 and 30 bands, I have been really struggling to determine my shape and fit and all that. Would it be ok if I private msg you? Is there a way to do that on here? I would really love to pick your brain :)

• Most find that the BM is the easiest to start with because the stretch lace top is very flexible. PL is the plunge. Most of us need to go up a size in the padded bras compared to the unpadded. Sometimes her bands run a size small but its hard to predict - just have an extender handy.

• I wouldn't recommend her plunges if you have soft tissue, you might fall out of it. The BM and SF are stretch lace on top and a great place to start.

• Cleo Spencer is very similar!

  Also I have a Cleo Breeze 34FF to sell if you're interested?

  34FF - Cleo » Breeze (9025)

• YES, I am very much interested!! Not very accustomed to Bratabase, can you send me a PM?

• The reference size is a very very basic average of the bands and the cups (independently and then put together) of the bras you've added. It does not contain any special sauce to calculate that. It's purpose is to allow the size and you to identify yourself as a reference size.
  The site dumbly obtains one based on bra info but you can set it yourself here https://www.bratabase.com/profile/update/ - The idea is that this is the size you "identify as".

  The recommendations use data from a bunch of places and relate it with all the other users' data on the site to obtain a set of recommendations you should get on each brand and on each model. The final "32FF-34G" range suggestions you see is a summary of the sizes you've been recommended. This computation is much more complex and takes a few seconds to obtain on demand only after you've entered breast measurements. The summary was only added because users ached to be displayed a **bra size** without any relationship to a particular brand or model as standard calculators do (something that cannot be purchased). But the real recommendations is the list of models in each particular size that you get suggested.

• Thanks for the explanation. I get that people "just want to know their size" :)
  Now I'm wondering if I've made some measuring typos if its based on the bras that I've entered. It's just weird that the average isn't near what I'm actually wearing.
