Vested Gentress was established in 1961 by Bud and Naomi Jackson and was based in Valley Forge, Pennsylvania. Their factory was located in Trappe, Pennsylvania, about twelve miles from Valley Forge. The company was known for whimsical screenprinted fabrics, many of which were designed by Bud Jackson. These fabrics were made into dresses, slacks, and skirts. They also had a line of golf wear. The company closed around 1985.
