The Racier OTK: Right before she dyed her hair back to all black, Katy Perry made an appearance in over-the-knee socks layered under a pair of platform sandals. While OTK socks can be more intimidating to pull off (cutting off circulation in the femoral artery, for one), they do make for an edgier, sexier version of the trend.

The Sporty-Chic Look: Off-duty model Ming Xi paired athletic-stripe socks with her sneakers. (I actually see this look quite a lot in Brooklyn and not on the soccer fields.) It's somewhat literal but, hey, totally comfortable especially in tricky spring weather.

So what's the verdict? Are you into knee socks for spring? Which of these looks do you like best? And most important question: Will you wear them?
