Trimfit was established in 1921 by Arnold, Harry and Robert Kramer. The brothers worked in a family-owned store in Manhattan, and saw an opportunity to wholesale hosiery to merchants in New York.
1949, Trimfit opened a state-of-the-art manufacturing facility in North Carolina. Soon after, the brothers purchased a manufacturing facility in Canada and began manufacturing and selling its products to Canadian customers.
In 1981, Arnold passed away and his sons assumed responsibility to run the company. Under their leadership, the brothers continued to build the brand's recognition as the retail landscape changed. Over the years, Trimfit has garnered many accolades and awards, such as the Ernie Award from Earnshaws Magazine as Most Outstanding and Recognizable Name in Children's Hosiery.
