+1 on:
- pack your work clothes (I get away with just a fresh shirt in the winter)
- don't ride too hard
- use the last 15 minutes as a cool down
- deodorant (I use one of the "crystal" deodorants. I was skeptical at first, but it works like a charm by preventing the stink producing bacteria from getting to their food source, i.e. your sweat)

I'm not a fan of trying to cover up stink with perfumes, but to each their own.

Also, do you eat breakfast before you ride in? (hope so!) If you're eating anything pungent (sausage, onions/garlic, eggs, ...?), that will be coming out of your pores with your sweat. Just something to consider.
