It's the question on every sunglasses aficionado's lips this holiday season. What sunglasses does Cheryl Cole wear? The pop starlet and former X factor judge posted snaps of her Christmas holiday in South Africa we couldn't help but find ourselves dying for a pair of her Cutler & Gross dark turtle aviators to call our own.cheryl cole cutler and grossA Pret customer favourite, the dark turtle aviators from Cutler and Gross look gorgeous on Cole. We love the unusual rainbow mirror lenses and think they are perfect for soaking up the Winter sun. Cutler & Gross make some of the most gorgeous mirrored aviators. The Cutler Gross Petrol Green aviators are perfect if you're looking for a more subtle effect, but if you're looking to go all out we can't get enough of the Red Wine lenses.We love the mirrored lens trend here at Pret and have it pegged to be a biggy for this Summer. Will you be trying it out?
