CHOOSING THE MOST FLATTERING SUNGLASSES—We’re all for choosing whatever pair makes you happy. But certain styles do flatter different face shapes. A good trick? Choose frames that contrast with yours. If you have a round or oval face, square frames are your best friend. If your face is more square or heart-shaped, round frames are super flattering. And don’t be shy about bright colors - it’s a good way to let your personality shine through!
