I need some new sunglasses (and have been spurred on by a recent post about replacing sunglasses), but I am still uncertain about how to choose. I've read Angie's post about frames for glasses and did some trying on today, but haven't got much further yet.

This is a blurry picture of my face:

I think it is rectangular and it is not that large. I have an olive complexion. I was wanting to get some oversized ones, but now I worry it might be overwhelming.

Any thoughts to push me forward on my journey? - particularly about size and shape - I was thinking of a light frame or even a blue or green colour.
