I initially hesitated buying this, but finally purchased it to match my daughter's swimsuit in advance of our vacation. I read a prior review that it was the first postpartum swimsuit for another purchaser as well... as soon as I tried it on, I was so, so glad I had bought it! The quality of the fabric is wonderful and it made me feel more comfortable than any other swimsuit I've worn. It is so flattering. I purchased a M to make sure the chest was large enough (I am 5'4", 130 lb, 34DD / breastfeeding) and upon seeing it, was a little afraid it would be too big. However, it fits great. I could have worn the S, but the M is not too tight / doesnt squeeze and it fits in the chest (my concern with a S).
