I personally despise seeing a collar worn upwards on a polo shirt, unless it was just a mistake. In England some people seem to have the idea it's cool to wear it up. Especially Jack Wills. The worst thing is now people wear TWO polo shirts with BOTH collars up. Your views? That's a sweater and a shirt, not two shirts. I think it looks good on a lot of women. Not just polos, but blouses too. It sort of frames the face.
