but how do you dress for work and cycle?

Me and Jeff biking w/Muscogee indians in Macon, 2012

its easy once you embrace it. just buy a-line skirts, boots, skinny leg pants, lots of fun $1 gloves at target, and scarves for winter. a good jacket with windbloc is pretty key to winter riding. i dont deal so much with the rain gear b/c i dont live in seattle or portland. if i did, i'd be gettin some new gear.
meanwhile i leave enough time to cover my 2-4 mile ride such that i roll leisurely thru my community, check out folks mailbox gardens, wave at neighbors, and enjoy the cruise to work. i'm not sweaty b/c i'm not rushing, even in summer. now i do have a desk fan at work just in case a commute gets sticky. but really a quick freshen up with say a lovely scented baby wipe, a moment in front of the fan and one is ready to go.
oh, i also have crazy curly hair and i havent met a helmet yet that can defy it, so no muss with the hair.
all in all, you have to want to be out there on the bike, you dress for it, you ride like you own it, and you love it. pave your own way, and fill it with your own style. it gives you a good excuse to transform a wardrobe with a specific goal in mind. oh, a some velcro leg wrap bands are key for keeping the cuffs outta the chain. and those 'slap band' styles, wrap right around the bike tube when not is use. keep it all loaded and a bike station by the door of your house so when you head out you have all you need.
here's some facebook album pix over the years of how i've dressed for commuting to work, my bike (a hybrid with city tires), and a link to the real cycle chic going on over in copenhagen. enjoy the ride!
