Introducing the MK2231U St. Barths, a refined expression of Michael Kors sunglasses design. This square sunglasses silhouette features a sleek, black injected front that frames the eyes with quiet confidence. The Dark Grey solid lenses complement the frame, delivering a sophisticated gaze for city days and seaside escapes alike.

Thoughtful craftsmanship underpins every detail: a lightweight injected front paired with slender metal temples for a refined, durable build. The lenses are polyamide for clarity and resilience, finished in a classic 54mm width with a 48mm height, bridge of 17mm, and temple length of 140mm to suit many face shapes. The universal fit (Geofit) ensures a comfortable, secure feel whether you’re commuting, working, or unwinding in the sunshine.

Prescription-ready options are available: on the product page you can buy the frame alone or add prescription-ready lenses that we will fit to your chosen style and ship to you in 8–12 days. This service aligns with Ardor Eyewear’s promise of authentic, premium eyewear with expert lens customization.

Face shape suggestions: The square silhouette is particularly flattering on oval and round faces, providing balance and structure. It can also add architectural contrast to square faces. If you have a heart-shaped face, you might prefer frames with softer angles for harmony with your cheekbones.
