Tiffany Trump attended a state banquet at Windsor Castle during U.S. President Donald Trump’s UK visit, wearing a custom-made blue quartz haute couture gown by Lebanese designer Saiid Kobeisy. The white-tie event, hosted by King Charles, welcomed 160 guests, including Trump and Apple Inc. CEO Tim Cook.

Styled by Toni Breisse and accessorized with jewelry by Samer Halimeh, Tiffany’s look was completed with a beaded clutch also designed by Kobeisy. The designer described the gown as a blend of heritage and modernity, crafted to embody elegance and a commanding presence.
Tiffany, 31, has a history of favoring Lebanese designers. At her 2022 wedding to Lebanese-born businessman Michael Boulos, she wore a Grecian-style gown by Elie Saab, a nod to her husband’s heritage. Her mother, Marla Maples, noted the gown reflected their Lebanese-American wedding. In 2025, Tiffany also turned heads at the Inaugural Candlelight Dinner in Washington, D.C., wearing a custom chocolate-brown chiffon gown by Zuhair Murad, featuring an asymmetric one-shoulder neckline and a dramatic cape-like sleeve.
