Not sucking at image editing + having common sense usually rectifies the problem.

get a mirror that's warped at the edges in the opposite direction to your photoshopping? idk.

doesn't matter though, you're honestly better off not shooping your waist that small/chest that big. even if the lines on the wall were perfectly straight, your torso still looks freakish in that pic. it would frighten off more girls than your actual body would.

possibly unrelated: you also have kind of a vacant/traumatised expression in that pic.

Cut out your body and set it as a new layer? That said, it looks horrible and anyone with half a brain would see that it's fake.
