What can you wear with striped knee-high socks?

Well, firstly, it depends what colours they are. If they're quite bright, I'd go all out and mix and match patterns in the outfit. But if they're dark, I'd keep it to the same sort of colours. Of course, it all depends on your style. I'd wear a skirt, as I really don't think any kind of trousers go with knee socks. For shoes, I think almost anything goes with them, really, but I'd wear sneakers.
