Introducing Michael Kors MK4178 Gustavia, a women's square full-rim eyeglasses that exude refined confidence. As a standout piece in Ardor Eyewears authentic designer range, this frame delivers designer eyewear luxury with a contemporary, architectural silhouette that adapts from boardroom polish to evening ease.

Crafted with an injected front in glossy Black, the Gustavia presents a crisp 54mm eye size, a 16mm bridge, and a 140mm temple length. The square frame delivers stately lines while comfort remains paramount, aided by adjustable nose pads (Geofit) for a tailored fit that stays comfortable through long days.

Prescription-ready customization is available here: you may buy the frame only or add prescription lenses that we will fit to your prescription and ship within 8–12 days. All lenses are prepared to Ardor Eyewears exacting standards for clarity and accuracy, with options to suit your vision and lifestyle.

Face shape guidance: the square full-rim silhouette tends to flatter oval and round faces by introducing balanced lines, while heart-shaped profiles can enjoy the bold brow line for a modern, confident look. If you have a square face, you may prefer softer silhouettes; nonetheless, Gustavia makes a striking, architectural statement for discerning style.

Style, color and delivery: this model is offered in a Black front (Front Colour Detailed variant includes Wisteria), aligning with a luxury aesthetic that complements professional wardrobes and evening wear alike. As a UK-based, official stockist of designer eyewear from brands like Michael Kors, Ardor Eyewear guarantees authenticity, pristine packaging, and a seamless online shopping experience, plus easy prescription customization and fast fulfillment.
