The daughter of a tailor, Trigère was able to operate a sewing machine by age 10 and often assisted her dressmaker mother. Shortly after leaving school, Pauline was employed as a trainee cutter at Martial et Armand in the Place Vendôme, Paris. While there, she met American designer Adele Simpson, who told her about the wonders of the New York fashion world. In 1937, at 25 years old, she moved to New York where she first found work at Ben Gerschel and later became assistant designer at Hattie Carnegie.
In 1942, Trigère opened her own fashion house, which was managed by her brother Robert Trigère. Her first small collection of 12 dresses was taken to department store buyers all across the country and by 1945, Trigère was a respected New York label. She received her first Coty Award in 1952. In the 1950s she started to produce costume jewelry to accompany her outfits, as did many other fashion houses at the time. Her clientele included many famous women such as the Duchess of Windsor, actress Claudette Colbert and singer Lena Horne. Trigère is also cited for designing Patricia Neal's sophisticated wardrobe in Breakfast at Tiffany's, although other sources credit Edith Head with Neal's wardrobe in the film.
