some people are naturally shaped like that but forcing yourself to have a shape that you didn't have before is bad for you
But anybody can be naturally shaped like that as well. I don't see the harm, all your organs still function the same.
it seriously messed up your body people argue with ne all the time saying it's just fine when it's not
and then pregnancy pushes everything up and out lol.
Don't get the body shaper and a corset confused though. This is what women's body's look like after using corsets or using waist trainers and over time getting them smaller and smaller. that's not what happens when you just need something to pull it all in.
