Here at Portlandize, we believe it’s important to look good while riding your bike. That doesn’t prescribe a particular style or genre of dress, but just means that you should wear what you feel good in while riding, just like you would while walking or riding the bus or whatever.
I just found a quote from Mark Twain which confirms my belief that dressing well is important:
“Clothes make the man. Naked people have little or no influence in society.”
So there you have it. Get your clothes on, get on a bike, and look your best, whatever/however that is. Happy riding!
