  I was under the impression that anything that made the upper bust appear as inverted/flipped UU shape causing upper roundness, was 'cakes on a plate'. Most brands offer a shallow on the bottom halfcup to force any/all lower tissue to bulge vertically toward the upper root to achieve this https://obsessedwithbreasts.wordpress.com/2012/12/05/cleavage-concerns/

  A shorter root will have a different presentation of cakes-on-a-plate than very tall roots as there is much more vertical area for the lower breast to displace to.

  But why is 'cups technically fit', getting the same size, still overflowing above the cup, happening?
  I turned to lilypadesigns blog to figure out exactly where my 'more volume same cup size' came from. Lilly Fong's method of determining size advises measuring one's entire IMF, vertical distance from nips/apex to IMF directly below, and the horizontal aspect across fullest part of bust (directly over the longest/fullest point from end of IMF to other end to get exact measurements; which can be used to sort out where the needed depth is occurring when compared with bratabase data of current bras worn https://www.lilypadesigns.com/pictorial-guide

  BCD measurement is used for comparing current cup apex (cup height minus about 1" for nip coverage), IMF length to underwire length, and HH with the cup depth. When 1 or more of these measurements is unlike the best fitting current size... that indicates a shape difference that can help one decide whether to go up/down a cup, or go for a different style more suitable for where the breast now needs it.

  How measurements inform cup shape & fit, is explained in depth here: https://hugsforyourjugs.blogspot.com/2023/09/the-relationship-between-horizontal.html

  Best of luck sorting this sizing thing, and enjoy the comexims as long as they still fit.

  • Thank you so much for your very thorough and informative answer! I will definitely look into it in detail and I’ll update with my findings.

  • So, I obtained the following measurements for both breasts:
    BCD = 6,5 cm (2,6 in)
    HH = 19 cm (7,5 in)

    How would BCD relate to cup height? And for cup death, jj clarified that the HH/horizontal perimeter doesn’t particularly match with ideal cup depth, so I’m even more confused now lol

    Anyway, I realized: 1. I am currently PMSing, so the increased volume makes total sense and 2. I placed the bra a tiny smidge too low, and because the band is tight, it stayed half a centimeter off from its correct place. Essentially, my bra was incorrectly positioned and it was therefore too shallow at the moment I took the picture… combine the two factors and the quadboobing popped out way more than needed.

    However, I might try a 55H… but I’m scared it might not fit for some reason. Thank you so much for your insight Holly_By_Golly !

    Check out data in the listings of styles you're interested in to see whether they're complementary to your BWD by comparing the gore and wing heights (if these are taller than your BCD, likely there could be issues with the cup fitting too tall, while shorter than BCD tends to cause lack of cup stability/control of motion); another method would be subtracting your BCD from the total listed cup height. Figuring out breast shape properties is also important to determine whether the cup shape will work for where you carry volume!
    Your BCD looks like it's typically bundled within the same sizing range as your HH, so the cup top's height should be 4.5" no more than 5" max I'd think?

    We're all a bit wary of sizes so being worried about another size is totally justified. Often we find each brand gives us a different size or has a wildcard style that's inconsistent running a size small or 2 sizes big. At this point the base has caught on I could be in 5 different sizes so learning to trust that instead of being absolutist with a specific band and number.

    My youngest was about 26G last year and gained 3" HH but no BCD, so height does not give her depth, and we aim for bras like Ewa Michalak M, 3DM, and CH (plunge version of CHP halfcup). I still have to tailor the straps closer for her narrow shoulders to prevent them from falling off or tall top from flapping about. She still has a 55J comexim which measures 8" HH/cup depth with cups 4.5" tall from the wire to the upper band, then 6" total cup height. Its gore is 2.5" and wing 4" which technically qualifies as 'plunge' but it never has fit like a plunge- she both drowns in the height of that thing and squirms for cup depth as it burrows down her ribs and the top of the cups are visible in her shirt's neckline- 'closest size available but shape not close enough', problems.

    A cup that doesn't have enough depth will push breasts backward into the chest wall and cause odd misshaping as was shown in the hugs for your jugs blog post on altering cup height and depth.
    Just as narrow roots can't simply be stretched wider to accommodate a wide cup, vertically short rooted breasts can't just go up as there's a strong limit to where their mass extends (both cases breasts may be shoved east west sideways into the outer wire which is painful and can cause injury). Even if it seems like one's breast shape might be shallow, whenever breasts have more surface area (roundness) than the pattern can accommodate, it causes tissues to become compressed not UP, but BACK into the body flattening their shape to the sides of the root where the IMF is (breast crease). It creates in the cup quadding. The internal tissue must be fluidic and low mass for this to work.
    
    As far as malleable breasts are concerned, everyone is different. Unfortunately not all breasts can just shapeshift to fill a tall cup- otherwise so many of us wouldn't be here dealing with it every time growth or shrinkage occurs; it would be super easy to squish into the next bra and wear whatever. People who have looser skin might find they can get away with some finagling or positioning, or those who're dealing with life change hormonal volume loss, or even others very squishy fatty tissue might compress upward... but I'd never say this is 'just how breasts behave' as it's pretty unique to each person, and essentially each breast. In my experience dense fibrous tissue resists and forces the cups away as it doesn't squish, at all.
    Because of this difference, I watch for well rounded drafting in a cup pattern to avoid cups fitting too small, while others who want a lot of control or external shaping, might look for straight lines and more conical 'flat' patterning to compress tissue into a certain shape and limit motion. It takes time and skill to determine what works for any one of us, at any given time.

  I am thinking that the definition of "cakes on a plate" is a too small bra to give cleavage in low cut shirts. Great if that is what you are going for! I do think that you are right in thinking that the bra is too small if you are looking for a well-fitting bra that looks good under more high-cut shirts. The difference between the cup depth and your perimeter measurements is too much. It is such a cute bra and will perhaps give you a better fit in a larger cup. Hopefully the wire width stays the same in a larger size.

  • Thank you for your comment! I am seriously considering sizing up, at least for the PMS days… Question for you, does the cup depth match your perimeter measurements? I thought they had to be at least close, but jj once clarified that they don’t have to match because breast tissue is redistributed when supported. I guess it makes sense! Boobs are very complicated 3D objects lol
