They can make u look more in proportion rather than thin I think but in clothes if you have big boobs they can make you look big all over like some things suit small boobs more than big n some things suit big boobs more than small… a pocho or similar would make me look big because I have big hips and now big boobs so I’d look like a beach ball lol, I need to wear things that fit my waist n show I have shape if that makes sense xx
