I had a credit from a return and found a pair of chartreuse skinnies on the sale rack for $10. I'm wearing them today, and they are amazingly comfy. Not only that, but they seem to have more stretch and actually stay up without a belt. And the rise is not too low for me. In fact, I like them as much as my cobalt Current/Elliot skinnies, which do require a belt.

Just in case anyone wanted to give colored skinnies a try for cheap, don't rule these out. They're the "Divine Rights of Denim" line which seems a little better quality than their other denim.
