In the process, these youth derived, street derived looks entered the formal style lexicon, and have become standard fare. Both the women's and men's looks here, with minimal tweaking could be worn right now with zero comment.By the 70s, the young had discovered thrift shops, and the treasures of amazing, fun, and unique (to them) styles on the racks there. This spurred a huge retro fashion trend which manifested in companies like London's Biba department store, and the Fiorucci design label. The decades of the 20s 30s and 40s were all just far enough in the past for the young that they thought of them as cool, and funky. Sound familiar? Sure it does. The rage for all things 70s that swept the design world in the beginning of the 21st is a perfect example.
But the most vital point is this: now, street fashion has become its own game, spinning off into ever more subsets and groups of players.
