The Michael Kors BIERZO MK4140U is a square-frame optical built on clean geometry and refined material work. Its broad, structured silhouette sits with intention — wide temples, a defined squared lens shape, and a slim bridge that keeps the look architectural without feeling heavy. The acetate construction delivers both durability and a polished surface finish, making this a frame that reads as effortlessly put-together from across a room.
Available in five distinct colorways — Black (3005), Dark Tortoise (3006), Mulberry (3256), Camel (3555), and Bosco (4006) — the palette spans boardroom-ready neutrals to warmer, personality-forward tones. The bold square shape is particularly flattering on oval, heart-shaped, and round faces, where the strong horizontal lines add definition and balance softer facial curves. If you prefer a bolder statement, the Mulberry and Bosco finishes bring depth and color without sacrificing versatility.
Every pair sold at AllureAid.com is 100% authentic, sourced directly through authorized channels — so you receive exactly what the brand intended, complete with original case and documentation. We offer free shipping on all orders and a 30-day return window, so buying designer eyewear online carries none of the usual risk.
