Have any of you ever tried a "purseket" in your big slouchy bags? It's just a gizmo with lots of other little pockets, designed to keep all your stuff in one place and make it easier to transfer from one bag to another.
There are many variations out there on craft sites, but I think the idea is cool. I have yet to actually try it myself, though. One thing I often do, however, is use cheap pencil pouches to keep stuff from floating all over the place. It helps a little bit.
I love the look of super-structured classic handbags, like the Birkin, but I think my developing style is definitely RATE, and I would look silly carrying a classic bag like that. Half the time I am lugging around a bunch of books and laptop anyway, either in an enormous canvas tote bag or a very gear backpack. Some day I will find (or design) a truly chic-looking backpack for these occasions, but I haven't put that much effort into it yet.
Or, I'll just get a netbook.
