First: There's a difference between the tall tees we saw in the early 2000s and the long tees we saw this summer. The latter is is more about playing with proportions and less about baggy clothes. Avant garde designers like Rick Owens and Ann Demeulemeester, and even brands like Kokon to Zai and Fear of God LA certainly adopted the look. Celebrities like A$AP Rocky and, on occasion, Big Sean led the resurgence of the trend.
