Carrera sunglasses for narrow face?

Alright so I'm looking for a nice pair of Carrera sunglasses, but I don't know which ones would fit a narrow face like mine (I'm a guy). All of the sunglass stores near me don't carry Carrera in the store so I have no way of trying them on. I was looking at the Carrera Cool model since they look smaller than the other models and I like the look of those the best. What do you guys think?
