The DiorSignature B1U sunglasses, the House's iconic line, are a modern and bold butterfly-shaped design. The grey acetate frame is distinguished by a play on curves and volumes for a graphic effect while the temples showcase the Christian Dior Paris signature embellished with Silver-finish metal lines that extend onto the front. Completed by gray Smoke lenses, the new essential style will lend a definitively Dior touch to any look.
