When you commute do you wear the lycra tights/knicks and a 'proper' cycling jersey (with team and/or component names splashed in bright colours) or just whatever conventional type clothing that happens to be lying on your bedroom floor at the time?

Also, are you considered a poser (or worse) if you are wearing a Trek US Postal jersey and you don't ride a Trek and you don't race?

I always wear the Lycra knicks/tights but usually only wear a t-shirt when commuting on the MTB. If I commute on the roadie I usually wear a 'proper' jersey (not a Trek UPS), so I guess I am a poser.
