I know how you feel, I have an ugly crooked long scar that even goes around my belly button. I still wear a bikini, except I have a wrap around over the bottoms to cover my scar on my belly. I think the wraps look cute and sexy, so I suggest you try one with a bikini before you decide against it altogether. You can always find a bathing suit that has
open sides but covers the tummy. Those are very nice too.
Take care, don't fret.
