Celebrities love Roksanda Ilincic! The Serbian-born, London-based designer got her start in 2005, when she debuted her line in London as part of Topshop's New Generation initiative. Ever since, her romantic-meets-edgy looks have been red carpet regulars, appearing on Dianna Agron, Kate Middleton, Gwyneth Paltrow, Keira Knightley, and more. “When I see women that I admire wearing my dresses, it gives me extra energy and this desire to be even better and to keep doing what I'm doing,” the designer told us at the British Fashion Council’s London Show Rooms event in Los Angeles. Her signature vibrant, colorful pieces, which often feature peek-a-boo cut-outs and perfect draping, can be purchased at and are also available to rent at And if you pick up one of her creations, follow her tip: “Women should follow their heart and feel comfortable in what they're wearing,” she said. “You should feel empowered, and always add a personal touch—your own personality to the garment.” See who else loves Roksanda Ilincic's designs in the gallery.
