As little as possible. I prefer to carry a small satchel bag because my shoulders are so narrow that larger hand bags always fall off me. Inside the bag I carry my purse (which is always so heavy because I only ever pay for things in notes, I don’t use coins, so my coin collection is huge until I meet a homeless person to give it all to). I also carry a few different kinds of lip balms or glosses, car and house keys, and my phone. That’s it.
