Steven Alan has got just the frame for large faces (and smaller ones too)

Whether' you've got a big melon or not, Steven Alan's new collection of aviators are the perfect answer for those who have trouble seeking out a wider-fitting (and flattering) sunglass. The aviators come in a traditional teardrop or navigator shape that are designed for larger faces, but still look great as oversized sunglasses on smaller faces. The sunglasses feature stainless steel construction, mineral glass lenses, and hypoallergenic titanium nose pads for lightweight comfort.
