We just keep things in several large bins, sorted by what belongs to which doll, since each of my girls has one. there's a bin for stuff for DD1's doll, one for DD2's doll, and a shared bin. My girls decided this method themselves and it works for us, as they are happy to paw through piles of stuff. If you're looking for something with lots of little drawers, maybe check out either a hardware store for the organizers they use for nails, screws, etc. Or if you want something in more of a "girly" color Joann's Fabric has some great craft storage with little bins, and they're almost always having a 50% off sale on organizing supplies.
