You can notice it on her stomach and arm but there are a lot heavier cases but thats nothing to be ashamed of. The Armor of a real Knight needs its scars
My Nephew also has light vitiligo, and I find the condition actually kind of interesting. It takes nothing away and nobody has ever cared that he has some weird spots.
I have sectional vitiligo on my left hand(and little lightness on my right hand and legs). I personally think it's pretty cool, and no one really minds, they ask me what hapenned at least once tho.
Nothing to be ashamed of
