MoonNeko, I assure you, I have never cosplayed a girl. Ever. So I'm not entirely sure which cosplay you're thinking of.
Youshi, you might try something to give a little more definition, like a contrasting brown or darker tan. For myself, since I'm fairly tanned, I use a dark brown cream makeup to create more definite shading and lines. Then use smudging and other makeup to blend it and make it more natural. I hope this helps a bit. I'll try and take some pics if I have the time, and give some examples of makeup you could use.
Cactusmomma, that wig color is awesome.
I envy your current productivity, Spork. All I managed to do today was chat with our Bellamy and wig swap with someone online.
REALLY??? Well then..the cosplay I saw you do I thought was a girl is clearly.. not a girl.. xD Ahaha I'm sorry XD You just looked soo cute in it, like a little kid with balloon pants XD I don't know the character sadly or I'd say but I'm not sure x_x;
The only way I'd be tan enough for Bellamy is to go get a spray on tan. I do NOT tan, I burn, peel, and turn back into a white pasty ghost. I hate my skin sooooooo much xDDD
