Second-skin over-the-knee boots are dominating wishlists, and we believe the Ivy design from Stella McCartney are one of the most stylish options. Firstly, they’re made from the label’s super-stretchy Alter Leather in a chic matte beige finish, and secondly, they have collars that expand to ensure absolute comfort. We think the 80mm heels will work for daytime, and long into the night. Stella McCartney Ivy faux leather over-the-knee boots
