My mom always asks me why I need such a big bag, followed by, "What if someone tries to steal it from you?" [She thinks big bags are easier to snatch and run with.] In which I reply, "They won't try to steal it from me because they will catch these hands." Mom then laughs and tells me to "just kill 'em with kindness." Which we both know would never get my credit cards back, but the point here is that you should carry a purse that you love so much you'd be willing to throw hands.
This STS Sweetgrass Tess Fringe Purse, for example, in all it's buckskin tan basketweaved, fringed glory, is worth every punch.
