Is there really a sufficient market to create lingerie for 4 year olds?

I’m really not even going to ask whether or not this is “okay,” because I can’t begin to imagine that the majority of the collective wouldn’t be as disturbed as I am by the images of children from infants to young teens dressed up in lingerie, while in provocative poses.
But, having said that, why would they create a line like this if there wasn’t a sufficient market? Would people actually buy this? And why??
Regardless of what I said above, I really do have to ask… how do you feel about this?
