ROFL - well - I'm one of those people. I wear arm warmers with sleeveless jerseys. The guy at my LBS said he thought it looked "sexy". (OK - made me rethink That look for a minute! ) Anyway - it can be chilly in the mornings in the mountains here but blistering in the afternoons hence - armwarmers for the forearms and biceps, sleeveless for the ride home. I never thought of the evening dress look. Might need to go home and put "sparklies" on my arm warmers now!
