I actually kinda like them...my brain is making outfits with them. I like the idea of wearing them with tailored gauchos or with cuffed jeans so you can see the shaft. But I do agree that if they're not done tastefully, they will look cheap or hookerish.
I like the zebra ones. I think they could look very nice with dark cuffed jeans and a red, turquoise or fuschia top. I don't really like the leopard ones though. I think they're wearable but only with pants. I agree that they'd look cheap with a skirt. Really, they're not bad. It's just a matter of personal taste and putting them in the right outfit.
