Mod was very popular in the late 60s, Twiggy is a great example. I'm fairly young so I wasn't alive then, but I still love Twiggy's style. The hippie movement was also very popular, and so were minis, loud prints, and bell bottoms. Designers Biba, Emilio Pucci, Nina Ricci, and Prue Acton were very popular during this period also.
