His couture training means that each piece balances flattering silhouettes with uncompromising comfort. As his career flourished, Guillaume also took on the role of Design Director for a diverse range of international celebrities, helping shape their distinct fashion identities. His work has been featured in top publications like Vogue, Harper’s Bazaar, W, and Elle, and his designs have appeared in the collections of many leading global retailers. In addition to his fashion line, Guillaume offers a luxurious home collection, including quilted bedding, plush throws, and cozy loungewear, designed to bring moments of indulgence and comfort to any home.
