It looks like Carrie Coon wears Krewe Webster Nylon sunglasses in The White Lotus Season 3 (2025).
The glasses have three dots on the temples, similar to Céline sunglasses, but the frame shape, gradient lens and the lack of dots on the front of the frame leads us to believe these are the Krewe Webster Nylon sunglasses - which was later confirmed by Krewe.
These same sunglasses are only available online at Krewe.
In The White Lotus, Carrie Coon plays Laurie, one of three longtime friends reuniting on a girls' trip. One of the other girlfriends, Jaclyn, wears many different sunglasses, including a pair of Krewe Brigitte sunglasses.
