Lulu Guinness adds unexpected details to a vintage-inspired silhouette in these L911 eyeglasses for women. Crafted with a sturdy saddle bridge for a retro aesthetic, the rectangular frames are made in lightweight but durable cellulose acetate. The wire-core temples provide a comfortable fit, and feature spring hinges that retain their balance to keep the glasses firmly in place. Rivet detailing at the temple repeats on the endpoints, adding interest to these rectangular glasses from Lulu Guinness.
