Skimpy Bikini
A bikini, one of the sorts that men always chase after when worn on a woman, due to the skimpy (or slim in case you don't know what skimpy means) fit that barely covers any woman parts.
"Wow, that burning hot chick is wearing such a Skimpy Bikini, it's like I have X-Ray vision on her and it's as if she's not wearing anything at all!"
