Scars
Hey Per210...and to anyone else for whom this might be relevant,
About the scar, I think as long a you can cover it up it shouldn't be a problem. Even skin conditions like acne and eczema are apparently acceptable as long as they are managed well, so I dnt think it'll be much of a problem.
I have quite a few scars on my legs myself, and I simply used concealer to cover them up. Perhaps a good concealer could cover yours up too.
