What's "DILLIGAFF"?

Someone else mentioned they wear spandex knickers under shorts when it's cold. So maybe I'll settle for Aerotech shorts instead. Men's Commuter Bike Short | Multi Sport Short | Aero Tech Designs I can just wear long socks too instead of knickers underneath.

I guess I'm just not confident enough to pull of the knickers look. My main issue is that it looks weird when you're OFF a bike. I feel like I need a beret and a vintage golf bag to go with them.

BTW, I'm 45, a man, so can't do "capris" or "purses." haha.
