Doesn’t look it with that tight waistband, although for some the boobs are the first thing to grow. She’s attractive, it’s just a funny effect created by a too-tight bra.
My wife is a petite and she is 4 months pregnant ,with boobs like that no waistline yet just a little bump..
I was mistaken i believe the pic was taken after she gave birth but continued breastfeeding for a long time...
