NEW YORK, NY, UNITED STATES, July 27, 2026 /EINPresswire.com/ — Margaret's the Couture Cleaner Enhances Its Luxury Handbag Restoration Know-How with Sotheby's Institute Authentication Credential.
Margaret's the Couture Cleaner, a nationally recognized frontrunner in premium garment care, leather restoration, and couture preservation, has announced that Chief Marketing Officer Katia Graytok successfully completed the esteemed Handbag Authentication master program at Sotheby's Institute of Art in London.
This certification further reinforces Margaret's premium handbag cleaning, leather restoration, and preservation offerings by increasing the company's understanding of brand-specific design, materials, and manufacturing methods employed by the globe's top fashion houses.
Conducted at Sotheby's Institute's Bedford Square campus in London, the rigorous five-day course concentrated on verifying luxury handbags through meticulous scrutiny of craftsmanship and construction. The curriculum examined iconic designs from Hermès, Chanel, Louis Vuitton, Gucci, and Dior, with lessons covering leather grain identification, stitching methods, hardware engravings, typography, date codes, and other brand-specific production traits used to differentiate genuine items.
Even though Margaret's does not offer financial valuations or commercial authentication services, this specialized instruction improves the company's capacity to maintain the structural and visual qualities that characterize luxury handbags. Knowing how each fashion label builds its products allows Margaret's artisans to devise cleaning and restoration procedures that safeguard the features collectors prize most.
"Preservation begins with understanding how an object was originally made," said Katia Graytok, Chief Marketing Officer of Margaret's the Couture Cleaner. "Our responsibility is to restore and clean luxury handbags without compromising the craftsmanship that makes them exceptional. This training provides another layer of knowledge that helps us preserve every stitch, embossment, finish, and construction detail entrusted to our care."
The certification complements Margaret's dedicated leather restoration division, headed by a former Hermès artisan and supported by a group of master leather craftspeople. Collectively, they provide luxury handbag and leather restoration services, including precision cleaning, conditioning, color restoration, edge refinishing, hardware polishing, structural repairs, and lining replacement for customers across the United States.
Margaret's serves clients through executive locations in New York City, five Southern California boutiques, and its national CleanByMail service, which enables collectors, luxury retailers, museums, and couture clients nationwide to ship handbags, garments, shoes, and accessories directly to Margaret's restoration facility for professional evaluation and care.
