While it is creepy, many people think that little kid's underpants are cute. They have those thick, colorful boarders at the seams and come in fun patterns. The Underpants Purses aren't made from real underpants, which at least tones down the creepy factor a little bit.
A small zippered case that looks like a pair of kid's underwear is stupid looking. Why would you want this? On second thought, don't answer that.
I have a sock coin purse---is that creepy too or amazingly awesome?
