Fun and funky, round glasses perfectly channel the popular vintage trend, but which faces do they suit best? One of the main rules when it comes to choosing frames is to select those that suit your face shape. With that in mind, round eyeglasses tend to work best if your face is angular rather than round. Square, oblong, diamond and even heart-shaped and triangular faces can all wear stylish round frames if they choose the right size and color - and of course, we have hundreds of great combinations to choose from at Express Glasses.
