What: The Woodstock Music & Art Fair was a three-day festival that took place in Bethel, New York (and not Woodstock, New York, pop trivia fans) in August 1969, set the template for the modern music weekender and came to define a late-'60s counter-cultural moment. But you probably knew that already. Fashion-wise, Woodstock is a summery update of the classic rock 'n' roll styling that we've been seeing for a few seasons now.
