Richie's shirt has been factory reproduced by CTVT. The reproduction snaps from the opposite side and the pattern of the stripes are different, although the color scheme is the same.
Richie wears a letterman sweater that is different from Potsie's letterman jacket. This sweater has been reproduced by CTVT. The reproduction is shorter at the waist and the "J" on the front of the sweater is screened on, while the original has a raised vinyl letter. CTVT also added a screened "Jefferson High" on the back of the sweater that didn't exist on the original version.
