Size Purchased: S
Usual Size: XS
I'm 5'3 127-129 lbs depending on what day of the week it is lol. I normally wear an xs in FN jumpsuits but because of the chest area I got a small (I'm a natural 32DD) and this jumpsuit fits perfectly and hold the twins up and in place lol. Has a little stretch and is fitted, if I would have gotten the xs like I normally get the chest part would have been too small. Can't wait to wear. Hope this helps
