The Styled By Collective is a private client styling house founded by Hayley Sullivan Marrero in 2021. Based in Los Angeles, New York, and Atlanta, the company works with women globally by inquiry and referral, creating and managing wardrobes tailored to each client’s personal identity and lifestyle. Its approach centers on choosing each piece for the wardrobe it will join, rather than for a passing moment, and providing ongoing, individualized care.

Services span wardrobe membership, closet editing, haute couture, high jewelry, bespoke bridal, event styling, travel styling, and editorial and production work. The team also supports sourcing, garment selection, fittings, atelier coordination, and wardrobe planning across occasions and locations. Bridal clients can access bespoke gown construction through the company’s atelier, while travel and event services help clients dress for specific plans and settings. The Styled By Collective describes its work as building, managing, and protecting a client’s wardrobe over time. Inquiries and consultations are arranged directly through the company.
