maninaskirt,
Fear not your not alone! I quite often wear one myself. I commute Stirling-->Haymarket daily followed by a trot into work. Like you I have found that no one gives a monkeys, its just clothes after all. Particularly comfortable in the summer months!
I cycle at the other end of my commute, about 4 miles from home to Stirling station. Currently trying to get my workplace to support the Bike To Work scheme, but having no joy! I'm afraid the commute by bike from Stirling each day would be too far!
Cheers
