The trend that I like much better are the stockings/ankle boot combination. I like seeing leg shapes, tight high boots covers up too much I think. Even with trousers there tends to be an ebb and flow through the leg. That said this PARTICULAR boot is nice, I must admit! http://lordashbury.com
The woman in the large photo looks lovely–those boots are really interesting with the little floral bloomers!
And don’t forget that a lot of guys look great in over-the-knee boots, too. Looks with a heavily Gothic/steampunk/anachronistic twist may not be “fashion,” but they’re often terrific.
