i have the dreaded overhang. i believe maz (??) calls it a GUNT!! lol.
i am overweight, so it's probably worse than someone who is fit etc, but i know my aunt (size 6) has had 3 c/s, and has a tiny gunt.
i don't have a scar though, i have fast-healing skin. so if you're in fairly good shape, i wouldn't worry too much.
