My new favorite kind of boot is the over-the-knee. I look forward to chilly weather so that I can bust them out and spice my legs up with them. But here's the thing: the right pair can make you look chic, the wrong, not so. You'll know when looking at it which category it falls in. I already own a black leather flat one, but would love to add a luxurious suede heeled style to my collection. During my hunt, I came across dozens of unique boots that I would make mine, wallet permitting. And these Stella McCartney Thigh-High Faux Leather Boots ($1,385), which the designer herself owns, are the over-the-knee Holy Grail. More than boots, they're like buying a pair of hot leather legs!
