S efik Yilmaz Dizdar is a Turkish billionaire and a partner in LC Waikiki, one of the world's fastest-growing fashion retailers. He acquired the French-born brand in 1997 along with his partners, including Mustafa Kucuk, and transformed it into a Turkish retail behemoth. Under their ownership, LC Waikiki adopted the philosophy "Everyone deserves to dress well," focusing on affordable, high-quality clothing for mass markets.

The company has expanded aggressively beyond Turkey, operating over 1,000 stores in nearly 50 countries across Europe, the Middle East, and Africa. Dizdar also holds interests in the tourism and real estate sectors through his family business. Despite his immense wealth, he maintains a relatively low public profile, letting the brand's global success speak for itself.
