It's unfortunate to live in a place that's warm year round (with a couple of exceptions in the winter) when you LOVE boots! Nevertheless, I own more boots than any other type of shoe... =)
And over-the-knees are so much fun. You can throw them on with jeans for a little outfit boost and still be totally comfortable, or pair them with a skirt and tights, or a dress. Basically, you can find a way to wear them with anything.
I've picked a few of my current favorites from this season, some of which are affordable, and some of which my PhD feet will never slip into. Still fun to look, though, right?!
