The Duffer of St George is a British casualwear brand founded in London in 1984, known for its distinctive blend of heritage tailoring, sportswear and workwear influences.

Originally launched by a group of friends selling curated vintage clothing from market stalls, the brand quickly evolved into a fully-fledged label, combining British style with Americana and street culture.

This hybrid approach helped define a new direction in casualwear during the late 1980s and 1990s.

At its peak, Duffer was not only a retailer but a cultural touchpoint—introducing key global brands to the UK market and shaping the way consumers approached relaxed, everyday dressing.

Today, the brand remains recognised for its eclectic aesthetic and its role in pioneering modern British streetwear, with a legacy that continues to influence contemporary menswear.
