Advance refers to the money provided to a Model prior to the completion of a contract. Generally, modeling agencies will advance airfare or accommodations to a Model as an incentive for that model to work with that agency.
In the fashion context, "Advance" usually refers to Advance Pattern Company, a former sewing pattern company that was based in New York City and operated from the 1930s to the 1960s. The company was known for its high-quality and fashionable sewing patterns, which were popular with home sewers during this time period.
Examples of Advance patterns include dresses, skirts, blouses, and coats, among other garments. Some notable designers who created patterns for Advance include Edith Head, Claire McCardell, and Adrian. The company also produced patterns for children's clothing, as well as accessories such as hats and bags.
Today, vintage Advance patterns are highly collectible and sought after by sewing enthusiasts and fashion historians alike. They provide a window into the styles and trends of mid-century fashion and are valued for their design details and craftsmanship.
