I was posting in another thread when this topic came up and thought it'd be interesting to get a broader survey. I don't remember seeing a thread on this in recent memory, but forgive me if this is a duplicate topic! So.....do you have a designer bag that you've designated as your "beater?" Something you don't mind tossing on the floor, using on a daily basis, and getting a bit grubby? If so, which bag is it?
