Over-the-knee boots: it's about time

Helloooo, Dolly! (c) Just after the over-the-knee boots have been around for a few seasons have they finally made their way into my heart and possibly into my closet. I know I could've jumped on this very promising trend a while ago (and I'm actually surprised that I didn't) but at least I'm ready to catch up now.
As it turns out, the universe of over-the-knee boots is not just vast - it's the size of a few Yankee Stadiums put together and right now, I'm navigating my way among all those fancy, funky, sexy and downright irresistable dwellers.
So which one is it gonna be - classic? hip? risqué ? or...?
