I don't know, normal people wear cycling specific clothes I think. Just like normal delivery drivers wear jump suits with their name on the pocket or repairmen wear uniform shirts.
I think more people would notice a move star in a kit and it would get more comments and interviews if they hit the red carpet in a full kit don’t you?
I might not always wear a jersey to go places like shopping on my MTB but I never even get on the bike without a Helmet and bike shoes and most often padded shorts.
