The 1960s featured a number of diverse trends. It was a decade that broke many fashion traditions, mirroring social movements during the period. In the middle of the decade, culottes, box-shaped PVC dresses and go-go boots were popular. The widely popular bikini came into fashion in 1963 after being featured in the musical Beach Party.
Mary Quant invented the mini-skirt, and Jackie Kennedy introduced the pillbox hat, both becoming extremely popular. False eyelashes were worn by women throughout the 1960s, and their hairstyles were a variety of lengths and styles. While focusing on colours and tones, accessories were less of an importance during the sixties. People were dressing in psychedelic prints, highlighter colours, and mismatched patterns. The hippie movement late in the decade also exerted a strong influence on ladies' clothing styles, including bell-bottom jeans, tie-dye, and batik fabrics, as well as paisley prints.
In the early-to-mid-1960s, the London Modernists known as the Mods were shaping and defining popular fashion for young British men while the trends for both sexes changed more frequently than ever before in the history of fashion and would continue to do so throughout the decade.
Designers were producing clothing more suitable for young adults which lead to an increase in interests and sales.
