Who started it: Fabolous
Circa: 2001 

Fabolous was heavy on the throwback tip in the early 2000s, rocking a shit-ton of Mitchell & Ness. Big Boi to a certain extent did the same in the ATL, throwing on gear like Pistol Pete Maravich jerseys, but certainly not in the same way Fabo was. Almost 10 years later, younger guys like Wale started bringing the throwback trend back, appearing in videos rocking old Pittsburgh jerseys with coordinating caps and kicks, but Fabolous has always been rap's biggest proponent of the throwback.
