A week's worth of underwear, a few clean tops and a spare pair of jeans, just in case.

Oh yeah, toothbrush, razor and deodorant too.

pretty much this,
except I can fit a week's worth of tops in the space a single man's shirt would take up.
I also take another pair of shoes and a couple of skirts. This all fits into a small backpack.
