Like the name itself, these Christian Dior Black Tie OUX2K sunglasses are the accessory for looking dapper at your next formal event. Designed with the elegant gentleman in mind, these rounded frames feature tortoise acetate as well as a single bridge in silver-toned metal, matching the rims' frame against the tortoise layer. However, it's the arms that give these shades their artistry. From the mid-arm to the edges  transparent acetate covers a single metal arm which begins at the temple. The Christian Dior CD logo is engraved in the metal at the temple. Blue lenses offer 100% UV protection. These luxury Dior Black Tie sunglasses measure 50-21-150 mm and ship with branded box, case, lenses cleaning cloth and designer documents. Made in Italy.
