These skintight long shorts are self illuminating and change their color! WATCH OUT! These pants do NOT replace your avatar's pants when applying them! My Outline Avatars do not wear pants, so it is ok. But normal avatars at least wear those long black pants. If you cannot remove them or wear shorter pants then DON'T BUY these shorts! TRY TRY TRY before you buy! Check my neon catalog! Feel free to leave a review. ~s~
