In 1969, the first Gap store opened on San Francisco's Ocean Avenue. Its name referred to one of the topics of the day --- the "generation gap" --- and here 's an early example of the boutique\'s youthful fashions. Pale sage-green pants, made of kitteny-soft cotton. High-waisted, with wide, straight legs. A large brass "militaires equipements" button closes top. Two hip crescent-patch pockets. Brass Scovill zipper.
