If it bothers you, wear makeup and lipstick, and whatever woman's clothes you can under your ski clothes. Dress girly for apres-ski. You are still presenting as a woman even if your ski wear is blue or gray. RLE doesn't mean that you have to bankrupt your wardrobe budget or do without fun activities.
I still wear my old hiking clothes when I take the dog for a walk, because they are well suited to the purpose and bloody expensive to replace. But I am a girl and I am presenting as such, regardless of what I am wearing.
