You do realize that most bike commuters don't ride in their office clothes, right? We carry our clothes, do a sponge bath and apply deodorant when we get there (or shower if we're lucky enough to have a shower at work) and fluff up the hair using a hair brush and a spritz of water. I rode to work off and on (mostly on) for more than 25 years and never had a problem with being sweaty at work.
