You have a couple of different options in skirt length with your boots, especially if they fit fairly snugly on the calf. One of my favorite looks is to wear high boots with dark tights, and a short, straight skirt that hits above the knee. Balance the look with a chunkier top, or, as the weather gets a little warmer, with a casual top that has some substance to it.

You can also wear a longer, full skirt that hits slightly above the top of the boots--you want just a little bit of leg showing for the most elegant and polished look. Again, it helps if you wear tights in the same tonal family as either skirt or boots.
