Wallet, sunglasses, gum, Tide pen, kleenex, small container of chinese herbs (my TCM herbs), folding hair brush, one Chico bag, sock knitting bag (which has its own items in it: sock on the needles, yarn, small crochet hook, over ear light, folded up pattern, row counter), cell phone, CTA card, Metra pass, pen, bluetooth headset, small Moleskine, cosmetics bag (lip balm, hand lotion, hair ties, nail clippers, nail file, Advil, Listerine Pocketpak). Whew!
Oh, and in the outside pockets: a small umbrella, house keys, work ID, and I usually put my stainless steel water bottle in the other side pocket.
Believe it or not, without a full water bottle this all can fit in a surprisingly light, and somewhat small bag!
