It really depends on how a girl dresses overall, as well as the face of their shape.If a girl dresses like a business woman and wears them, it will be kind of weird for her to warm them. But if a girl dresses casually, then that is fine. As for the shape of their face, if someone is skinny, a circular frame will be fine, as long as it is not super oversized. As for those with a rounder face, they should not choose a circular frame. A more edgy frame will be better in order to contrast the shape of their face. Big, circular frames will only make their face look more oval.I think it is cute if it is for style, but if someone wears them all the time, I think it makes them look stupid.
