It's pretty good, but it does slide around a bit. I wouldn't wear it with something that doesn't have decent structure on its own, but with a nicely structured strapless dress it does all right.
I convinced myself that this bra fit at the store because I thought it was so cute. I actually tried on two of this style that both said 34D on the paper tag. I did not check the internal tags because I assumed the paper tags from the manufacturer (not the store) would be accurate. The light colored one seemed to give quad boob, so I didn't buy it and chalked it up to manufacturing anomalies. Then, when I tried on the black/cream bra at home in order to put it in bratabase, I realized something was weird. And I happened to glance at the tag. I know I didn't purposely buy any 34C bras today, so it was super weird that the bra says 34C on the fabric tag inside, but 34D on the paper tag outside.
I am very thankful that the straps on this bra are long because most convertible bras have too short of straps for me. Additionally, the straps on this bra are a little too far apart for me unless they are crossed or pulled together in the back.
I just bought this bra and have not worn it yet. I'm guessing it will not be comfortable for all-day wear. However, it's quite cute, so I will probably wear it for shorter durations wear I want to feel sexy.
This bra seems to have a band tighter than most 34 bras I have tried before. And it only stretches a little. Beware of this if you are between a 34 and 36 brand.
Very pretty bra, it not my size at all. The cups are somehow both tight and not filled, and the band has a tendency to ride up in the back and get pushed downward in the front. Another down in the band/up in the cup situation for me.
