SIR of Sweden is a renowned brand that traces its roots back to 1925 when Valter Ljungström founded it in Vingåker, Sweden. At just eighteen years old, Valter couldn't form a company under Swedish law, so his mother, Hilma, registered and formed Ljungströms Konfektionsfabrik AB on his behalf. They named the brand SIR to capture the refined and sophisticated style of a British Gentleman.

From its humble beginnings, SIR of Sweden has grown into a leading brand in Scandinavia, specializing in tailored clothing. The brand's dedication to craftsmanship and tailored skills has been a driving force throughout its history. While the production process has become more automated over the years, SIR of Sweden remains committed to quality control and fine craftsmanship.

The design and pattern making still take place in-house, and the production is carried out in EU plants using premium fabrics sourced from Italy and other exclusive European mills. SIR of Sweden's product range extends beyond traditional menswear, with a growing focus on a ladies collection to cater to the increasing number of businesswomen. Today, Valter Ljungström's grandchildren carry on his legacy, proudly upholding the brand's founding values of high quality, skilled craftsmanship, and exceptional tailoring
