I think a purse would probably be more useful, at least for me since I carry a lot of stuff around, but if you don't carry a lot a WOC would probably be a good buy and it is a lot cheaper than buying a flap. Just be honest about how much stuff you regularly carry and get a bag where it will fit w/o being stuffed, that way you will actually use whatever you buy. I have small bags that are adorable but I never use them b/c they just don't work with my lifestyle, so I just look at them in my house basically.
