From the other side - I've never had a c/s and don't have a 'hang'. My tummy went back to its old shape but not the same texture. I'm naturally thin and put on half my bodyweight extra when I get pregnant so I have quite ridiculous stretchmarks (took about 3 years post baby to come to terms with those - nasty things) so my skin looks awful and goes all wrinkly depending on what I am doing, and if I wear jeans that are too low I get a muffin top of just skin. No fat, I lost 100% of the baby weight both times. So, I just wear jeans that are high enough to avoid the muffin top and tight enough to hold it all in. But no hang.

I'm assuming things aren't going to be so good after #3 so I've bought one of those elastic waist shaper doodats just in case.
