New York-based luxury duo choose Mayfair’s Mount Street for European debuts

New York-based independent luxury brands Foundrae and Adam Lippes are set to open their debut European stores on Grosvenor’s Mount Street in Mayfair, London.

Foundrae – a fine jewellery brand that’s attracted a following that includes Taylor Swift and Cynthia Erivo – will open its first standalone European flagship in July 2026, taking 2,300 sq ft at 119 Mount Street.

Adam Lippes, the American designer renowned for tailoring and sportswear, will open in June with a 2,100 sq. ft store at 9 Mount Street.

Both brands join a mix of luxury names on Mount Street, including Jessica McCormack, Simone Rocha, Toteme, Moynat, Oscar de la Renta, Rubinacci, Valextra, and Marchesi 1824 – the Milanese patisserie owned by Prada which chose the location for its first store outside Italy.

Henry Hunter, Mayfair retail director at Grosvenor, said: “Our retail strategy is centred on building a distinctive, complementary mix of brands that value creativity, quality and a more considered customer experience. Adam Lippes and Foundrae are fantastic additions to the premium retail line up on Mount Street, and attracting such respected independent brands for their first standalone European flagships reflects the enduring appeal of Mount Street Neighbourhood as a destination of choice for leading international brands.

“These new lettings tell a clear story in how luxury brands approach physical retail. There is growing demand for environments that allow for storytelling, craftsmanship and a deeper connection with customers – something Mount Street is uniquely positioned to offer.
