I very much enjoy nail polish. :D
I tend towards brighter colours, like I have a really nice green colour, a really nice purple colour, and pink, and neon green, and red, black, midnight blue, and a few more, but I can't really keep track of them because I have a lot.
They're so fuuuuuun. ^^
As soon as I can, I'll be painting them orange and black for Halloween, although I don't have my own orange nail polish so I've been waiting on my friend to bring me some, and she always forgets. D;
Oh, and since someone mentioned makeup, Eyeliner is pretty much equivalent in interest for me. :)
EDIT: Also want to get electric blue. I'll buy some once I get a job. <3
