what features do you like about your wallet/purse/handbag?

I love the fact that my purse is big. I have three children so sometimes my purse doubles as a diaper bag. As I'm sure it usually does with most mothers. I switch purses often though. I have a purse organizer which makes switching an easy task. I only use handled purses, not a fan of over the shoulder ones. Although some handles are long enough that I can put on my shoulder if need be. The purse I use depends on my outfit. If I am wearing a plain outfit; I wear a colorful purse and vice versa.
