Step into coastal-luxe living with the Michael Kors sunglasses MK2231U, known as the St. Barths. This premium square, full-rim silhouette captures timeless elegance with a sleek black injected front and Dark Grey Solid lenses. Crafted for days under bright sun and nights in the city, the lines are refined, the silhouette balanced, and the feel unmistakably premium. Ardor Eyewear guarantees authenticity with official packaging and a seamless luxury experience from a UK-based retailer you can trust.

Designed for lasting comfort, the injected front teams with slender metal temples to create a lightweight, durable frame. The polyamide lenses deliver crisp vision and edge-to-edge clarity, tinted in a classic Dark Grey Solid. With a lens width of 54mm, a lens height of 48mm, and a bridge of 17mm, this style offers a balanced fit and versatile proportions for a contemporary look. The frame features a Geofit of Universal Fit for a broad range of faces.

Prescription-ready customization is available on the product page. Choose frame-only, or select prescription lenses and we will fit them to your MK2231U and ship your completed pair within 8-12 days. Ardor Eyewear provides full manufacturer packaging, authentic design, premium materials, and a seamless online process designed for modern professionals who value speed, accuracy and luxury.

Face shape recommendations: For a square silhouette, frames like MK2231U typically flatter oval and round face shapes, adding definition and balance. If you have a heart-shaped profile, this design can still achieve a flattering contrast when sized to your features. Consider trying our virtual try-on or home trial to confirm your preferred look.

Designed for the city professional, these sunglasses pair with a modern wardrobe—from tailored suits to weekend denim—creating a confident, aspirational look. With authentic design, premium materials, and Ardor Eyewear's trusted service, you can shop with confidence from the UK's luxury eyewear specialist.
