Leg warmers aren't for everyone, but when fall rolls around I absolutely love them. Last year I picked up a couple inexpensive pairs on amazon (pink pair seen here), and while I liked them a lot, the material was thin, a little too stretchy for me, and left a lot to be desired. When I was in London in August, I saw this promising grey pair at Sweaty Betty and couldn't pass them up. Made from a thick, knit material, they're super tight (which I personally love for compression), and have a stirrup bottom which is nice for added warmth on the feet without compromising functionality. The top part of the leg warmer is sort of like a waistband, ensuring that it won't slip down the leg when you move. I really love that they're extra long, providing an added layer of warmth. They're pricey though, which is their only fault, and I've included a couple of more budget-friendly options down below.
