Thom Sweeney, the Mayfair tailor founded by Luke Sweeney and Thom Whiddett in 2007, has expanded its London flagship on Old Burlington Street by joining its townhouse at 24C to the building next door at No. 25. The expansion was announced on 30 September 2025, and Luxury London reported that it opened in October after construction pushed the launch back by several weeks.
The new space was previously the Stephen Friedman Gallery, which moved to Cork Street. The ground floor now holds the full ready-to-wear collection and larger fitting rooms. The first floor is a private area for bespoke and made-to-measure appointments, with room to show more commissioned garments. At the back is a walled garden open only to clients. The interior uses warm woods with a boating feel and polished chrome, in the same style as the brand's Los Angeles and Miami stores.
“The minute we found out we could link the two buildings, we knew we had something special on our hands.”

From one room to two townhouses
Sweeney and Whiddett met while working for the tailor Timothy Everest and started their own business in a small room on Stratford Place, according to Luxury London. They later moved to Weighhouse Street and then Bruton Place. Their first ready-to-wear collection launched on Mr Porter in 2013. In September 2020 they brought their two West End shops together in a four-story, 3,100 sq ft townhouse at 24C Old Burlington Street, with bespoke workrooms for their cutters and coat-makers on the lower ground floor.
Luxury London reported that a Thom Sweeney bespoke suit typically takes three fittings and 80 hours of handwork, with delivery usually within 10 weeks. Made-to-measure garments are made in the same Italian workshop as the ready-to-wear line.
A run of openings
The London expansion followed a busy period abroad. The brand opened its first New York store in SoHo in 2017 and a Los Angeles loft on Melrose Place in 2024. A 2,500 sq ft boutique in the Miami Design District, designed by Billy Cotton, was set to open in December 2024; Miami Living described it as the first stand-alone boutique in Miami from a British tailor. Luke Sweeney told Luxury London that a new flagship on Madison Avenue in New York was planned for the following spring.
What it means for buyers
For London clients, the main change is more room for fittings and a clearer split between ready-to-wear on the ground floor and private bespoke and made-to-measure appointments upstairs. Thom Sweeney sells all three levels of tailoring, so the bigger shop makes it easier to compare them in one visit. Our explainer on bespoke vs made-to-measure sets out the differences, and bespoke fittings explained describes what happens at each of those three fittings.
