Do or don't: Knee-pad tights

A couple years ago, I had a pair of knee-pad tights. They looked so cute with a dress or skirt, and I happily wore them to movies, dinners and parties. They made me feel pretty. Don't they remind you of something Zoe Deschanel would wear?

They ended up disappearing into the laundry, but I'm excited to get another pair for this holiday season. Thoughts? Would you wear them?
P.S. Remember these sexy tights?
