Exactly. I have a short commute, about 1.5 miles. Sometimes I walk. Sometimes I wear bike-specific clothing. SOmetimes I wear khakis, a sweater and a button-down. I work at night and what I wear at work does not matter (except that I spend A LOT of time outside, at night when it gets COLD. If you want to bike wearing a super man outfit, do so. If you aren't enjoying your commute, you are seriously missing out.
