I love knicker bockers! What are knicker bockers you ask? They are the 17th and 18th century form of what people call today "slacks" or "pants". Knicks (knix, or nix) were mostly worn by men in the 1600s and 1700s.
In my opinion, knickers are very neat. If you've ever seen an American baseball game, I'm sure you've seen the knickers being worn by some players!
Knickers look very comfy, and usually when I wear sweatpants, I roll them up to make them look like knickers (of course, I wear knee socks to get the WHOLE look and to stay warm).
