The least I ever carry is: 1. ID 2. Wallet (or sometimes, if it's a REALLY TINY bag, I leave the wallet behind and just take cash, credit cards and my Metrocard) 3. Lip color That's it. If I'm with my husband, I don't even need my keys because he has his. Mind you, though, this is only when I'm going out at night and carrying a very small clutch... usually, I have much more!
