So I went to the beach with my friends yesterday, and after looking through pics I took with them I realized I'm the only one with this weird line down the top half of my midsection. It's not abs or anything like that (I don't work out), so I honestly have no clue what it is. I'm actually pretty out of shape so there's no way it's toning or anything. I used to be pretty overweight (I'm 18 now but from 8-14 I was overweight), could it have something to do with that (extra skin or something)? Does anyone else have it? Or does anyone at least know what it is/if it's normal? If I could describe how it feels it almost feels like it separates the fat on the left and right sides of my body lol (I think you have to click on the pic to see the whole thing)
