Whenever you can
if your coach told you to wear a thong i'd take it up to the principle
a thong or man-thong and nothing else
A GIRL SHOULD WEAR A THONG WHEN SHE IS WEARING TIGHT PANTS OF SPADEX PANTS TO PREVENT PANTIE LINES SHOWING.
u should wear them when ur 18 having it
you should wear somthing sexy like a thong lots of girls wear them
Thong.
If you can see them through your wedding dress, then no.
a thong and no shirt
very tight unless it is uncomfortable for you
If they want to wear one they can as long as it's not visable.
