I want to be able to select more than one choice! It depends on where I'm going and what I'm doing. If I'm going out someplace (like a party or someplace with dancing) where I don't want to keep track of a purse, I try to wear something with pockets that I can use. Most days, my wallet is in my purse, but when I run out to grab lunch, I just stick my wallet into my jacket pocket, which works until summer when I don't have a jacket, then either I stuff some cash into my pockets in my pants if they have a decent pocket (women's clothing rarely has useful pockets...if any) or have to take my purse...I've tried just taking the wallet, but if I don't have pockets or a purse, then I end up having to juggle the wallet with whatever else I'm carrying at the cafeteria.
Of course, I'm not sure what you'd call it way back when I had a "purse" that was basically a wallet with a strap. That was my favorite...too bad it wore out and I've never been able to find another like it. It was perfect...if I had pockets, I could just take the strap off it and stick it in my pocket, and if I didn't have pockets and didn't have a free hand to carry it, just use the strap.
