Inside the arm of every pair of sunglasses are numbers like 54-18-140, and the first one, the lens width in millimetres, decides how much of the picture the glasses take. Small lenses stay precise, medium ones sit quietly, and large ones read as a statement.
Set the lens width, the bridge and your own face width to see the frame in proportion, then try it with sharp tailoring, a plain tee or a big coat. The piece explains the rule of thumb behind the result and what to check before you buy.
