I just don't get it

So I'm a cosplayer and tbh I really feel like I don't look good in cosplay, not because I'm ugly but because of my skin color. I don't understand why I think this way because there's so many amazing and beautiful/handsome black cosplayers out there but when I look at myself there's always something in the back of my head saying "you would look better if your skin was lighter" and I hate it so much. Even just going out with my friends I feel so out of place (I'm usually the only black girl). I know I might sound a little delulu and trust me sometimes I don't get it ether
