Just throwing a few out here...
1. Tight white top or tank top
2. Boy shorts with knee high socks.
3. Schoolgirl skirt with button up top
4. Any lingerie
5. Tanning oil...probably have to wait a bit for that one, huh?
6. Tanlines...see above
7. body paint.
I'm sure I'll come up with more
Thanks for sharing what you've already put up...they're great!
