has split-crotch gone mainstream?

everyday undies?

Seriously, since when are crotchless panties everywhere? I thought they were reserved for “special” occasions, and that they could only be purchased at places like Frederick’s of Hollywood. Now, I’m seeing them at Nordstroms, ShopBop, etc. Are they still being marketing as “naughty”? Or are they actually being considered everyday knickers? If so, what’s the point of wearing undies at all? If you aren’t covering your parts – why bother?

I don’t understand the hole in the back. Can someone explain THAT to me?
