Ah, yes, the decade of the tracksuit. Beloved by the likes of J.Lo, Paris Hilton, and Britney Spears throughout the early- to mid-aughts, Juicy Couture's terry cloth and velour sweatsuits are already a nostalgic item that certain celebs—not to mention the brand itself—are trying to bring back. Graphic T-shirts ("Team Aniston" versus "Team Jolie," anyone?), bare midriffs, and logo-heavy It bags also reigned supreme. (Hopefully, the trucker-hat trend will stay firmly in 2004, though some celebs are attempting to revive it.).
