Michael Kors MK2231U Square Sunglasses for Women — Free Shipping

The Michael Kors ST. BARTHS MK2231U is a bold, resort-ready square frame built for women who wear their confidence visibly. The silhouette leans oversized with clean geometric corners — a shape that reads equally at home poolside in St. Barths or navigating a city afternoon. Crafted with a lightweight acetate front and smooth temple arms, the frame balances substantial presence with all-day wearability. The 54mm lens width sits at a true statement size without tipping into costume territory.

Across the seven available colorways, there is a version of this frame for nearly every complexion and wardrobe palette. Black (300587) is the perennial workhorse, pairing with everything from beach whites to office neutrals. Dark Tortoise (30063G) and Luggage Tortoise — Polarized (40319P) warm up olive and deeper skin tones beautifully, while Mulberry — Polarized (3256T5) and Light Iris (40057N) offer a softer, fashion-forward option for fair or cool-toned complexions. Deep Red (400473) makes the frame a deliberate focal point — ideal for anyone who treats accessories as a signature. The square geometry works especially well on oval and heart-shaped faces, where the structured corners add balanced definition.
