 Irmak Su Guclu founded her eponymous luxury women’s ready-to-wear fashion label in 2021. The brand was born out of the desire to make women feel sophisticated, beautiful and powerful, with timeless garments that are impeccably tailored. A vision of modern luxury characterized her ready-to-wear collection. The brand’s DNA consists of cocktail and evening dresses created with multi-piece and removable pieces. Uncompromising in using only the finest, most luxurious materials, Istanbul-based and designed in New York City, the expert craftsmanship in every piece is evident from the precise cut to the meticulous finishing. ISG pieces are unique, and committed to women who demand lasting value in their products.
