Every time you go to Costco their is this hot girl who wears tight jeans everytime she wears tight jeans her underwear rids up should you tell her while shes working or when she goes intothebathroom?

well if she's wearing thong underwear she's wearing the pants and having the underwear ride up on purpose.

shes not wearing a thong. just normal pink frilly undies.

I'm standing by the "she's doing on purpose"
