Hailey Bieber attends the Tiffany & Co. Lock Event in LA

American model Hailey Bieber went for a bold and daring ensemble, and arrived in a completely sheer black dress at the star-studded Tiffany & Co. party at Sunset Towers in West Hollywood on Wednesday. The model, 25, was a smoldering vision in a Saint Laurent Spring/Summer 2023 see-through look, which also flashed her matching underwear. Putting her slinky and toned figure on show as well, Hailey looked impeccable in her black dress which also had full length sleeves and a high neck. The outfit was paired with black stilettos and an array of Tiffany & Co. jewels.
