In 1855 Charvet exhibited shirts and drawers at the Paris World's fair. The jury noted that Parisian shirt makers had an "unquestionable supremacy". Again, at the next Paris World's fair, Charvet exhibited shirts, drawers, vests and handkerchieves and the Jury noted luxury shirts were a Parisian "monopoly". When the king-to-be Edward VII visited the fair, he ordered Parisian shirts, as many other foreign visitors did, and remained a loyal customer of Charvet, "honoring him during forty years with a special kindness" (See List of Charvet customers). Charvet created for the prince of Wales a certain style of shirt collar, the stand-up turn-down collar, also referred to as the H.R.H. collar, which became very popular at the end of the 19th century (Figure, right).
