Psychedelic

Brilliant colors, eye-popping designs, luxurious fabrics--all these and more characterize the unforgettable fashion trends of the late 1960s and early 1970s. This was a turbulent, exciting era in our history, and clothing styles clearly reflected the fast-moving, youth-oriented culture we remember now with a sense of awe. Sophisticated or casual, clothing became an expression of personal feelings, ideas, and attitudes.
