Snake Skin Onesie Stylish & Unique
It has no size on it but is stretchy and adaptable I would say XS, S, & M with XS and Small being most ideal 
its hard to get measurements because of the way its cut but I would say around 28-30 waist around there is good
and those with 32-34 a or b bra sizes would be best unless you lower the zipper to give you more boob room
Has some cute sequins on it too
