So... I found a few odd threads about this on cosplay.com and none really answered my question..
I have a large brown birthmark on my upper calf - Like 3"x1". Maybe 4"... And it's solid.
My question is not just how to cover it- since normally I opt for boots or pants to cover it... But this costume will have mid-calf or knee high socks... Not sure which yet that will be white. So I'm guessing if I were to put foundation and powder on my leg and then ease a sock over it, as I walk and move throughout the day, the makeup will inevitably wear off (be rubbed off). And dirty the sock. I don't care so much about the sock, as the mark.
Would this be a mark that'd be okay to not cover, even though it is so large? I'd rather cover it.
But my thought right after the make-up coming off was some kind of acrylic paint that I've mixed the color to match my skintone. Since that won't rub off as easily, but because skin flexes, it probably would split/chip...
Please ignore the odd angle... I was balancing on one leg with my right leg up on the bed.. xD;
