Keira Knightley Charms in Sheer Lace at Biarritz Festival

Knightley chose a two-piece ensemble consisting of a delicate white lace slip dress and a matching long-sleeved, round-neck cardigan, buttoned all the way up. The open floral mesh fabric of both pieces created an almost completely sheer effect, hinting at the silhouette beneath with grace rather than overt display. The midi-length dress, coupled with the classic cardigan, offered a sophisticated take on the sheer trend, moving it beyond the beach and firmly into film festival chic. To ground the airy white, she opted for a pair of Y2K-coded black heeled sliders, a surprising yet effective choice that added a touch of relaxed cool.

Her blunt bob, styled with a center part and soft waves, perfectly complemented the light, breezy feel of the outfit, allowing the intricate lace pattern to truly sing. Knightley’s consistent embrace of elegant white looks, as seen in her Wimbledon appearance last July, shows a clear comfort and confidence in this palette. Here, she masterfully blended traditional romance with contemporary cool.
