I'm 5'2", 110 lbs, 32a Target brand bra (most of the time anyway), measurements are 28/25/37 without a bra on.
Quality is totally there for the price and the dress itself is beautiful, and the color is almost identical to the swatch which was ordered almost a year prior to the dress. The material is exactly like the swatch, which feels nice. Order swatches, they're worth it.
The bust is very modest and covers basically the whole breast. I'm curious if this is just because I'm petite, however the measure from top of the sweetheart neckline to nipple is quite long.
And while I ordered custom sizing and it turned out way too big, it might be my fault since I'm a 28/25/37 without a bra on and ordered a 32/27/37. I have no idea if they changed their instructions since I ordered, but I remember triple checking and following the instructions to a T. But this dress is freakin' huge, like way bigger than a typical 32 bust. I doubt a size 0 would have done me any good.
Overall I'm really happy with the dress. I would definitely buy from here again. Just wish that custom sizing would have saved me from having to get it altered.
