One-piece swimsuits were still popular, but the new two-piece suit had plenty of fans too. The materials used to make swimsuits today were not invented yet, so suits were made from rayon jersey and rayon jersey blends with knit cotton linings. Many suits had accent panels of a velvet like rayon velour. Some also featured ruching on the front or side panels that were both pretty and figure flattering. Any color could be found on a swimsuit, but patriotic colors were popular as well as floral patterns and polka dots. Suits fastened with small buttons or metal zippers in the back.
