The Thiéry brothers opened a first cloth shop in Saint-Ghislain, Belgium, in 1841 under the name Thiery frères. The family business then expanded across France; the founders' grandson Armand gave his name to the brand in 1963.
After the textile crisis of the 1970s, the company was sold in 1991 to the PPR group, then in 1995 to Bidermann. That same year the family of Lucien Deveaux took over the French assets of the menswear group; the current company dates from 1996.
The brand diversified with Toscane (2007, women's plus-size fashion) and Edji (2011), the latter two merging in early 2024. Based in Levallois-Perret, it has several hundred stores in France, Monaco and Belgium.
In April 2026, Armand Thiery became title partner of Louis Burton's Ultim.
