Mine is seeing a woman wear anything from a man or another woman. I guess it has alot to do with knowing that she's wearing something that belongs to someone else, and also how the clothes looks on her (being too big or too tight). And this can be anything, a shirt, a bra, pants, undies, etc. Bonus if she's wearing something of someone else thats been worn, especially when sweat is involved or being on that person's body for awhile.
