Saint Laurent Square Sunglasses SL M40 003 Black 54mm YSL

The best way to determine your size is to compare the measurements listed on the product page with a pair you already own that fits comfortably. Sizing is most comparable between frames with similar shapes and materials—for example, a 54mm acetate rectangular frame will generally fit more like another 54mm acetate rectangular frame than a 54mm metal pilot frame. Consider lens width, bridge width, frame shape, and material when comparing sizes. We also provide the overall frame width when available to help determine fit.
