STYLETHREAD -- LET'S TALK SHOP!

I recently took a new job, and have to run across campus from time to time. Right now I am lugging a too big purse, which isn't big enough when I am running my errands. I'd like to trade this big purse for a smaller purse and a crossbody meets messenger type bag.

I'd like something in black or gray as my purse is often a color. And, I'd like something professional enough to carry it to work, to meetings and to the Dean's office, but not too stuffy since my office is pretty casual.

Has anybody seen anything that fits the description, and could hold a few folders, a pair of shoes and possibly a lunch?
