A nice cotton blouse, like the one here, works well with jeans or khakis. With a cut that's slightly more dressy than your average t-shirt, the blouse looks polished but feels just as comfortable as your favorite cotton t-shirt.
A pair of tasteful heels rounds out the look. These shoes are simple enough to go with a whole array of pieces, and they are also comfortable enough to withstand long days on the job.
