I am 152 pounds, 36 chest 27 waist 41 hips. I am usually between a small and medium, but purchased a small. super sexy jumpsuit!! but very very tight. although it’s stretchy, it’s tight and doesn’t allow for the good bum “jiggle”, my boobs slip out the sides without tape, and extremely tight around the legs/capri area. feels like compression socks lol. I would size up. I also bought the amber snatched jumpsuit which is the exact same material, but I purchased in a medium and it’s much more comfortable for reference if you have that one.
