Starsky and Hutch share a few items over the course of the series. The most famous example is this red sweater. It is what I call “tag wear”, a garment only seen in tags.
Starsky/Hutch wears it in:
01-21 A Coffin for Starsky (Hutch)
02-18 Survival (Starsky)
02-19 Starsky’s Lady (Starsky)
02-24 Murder on Stage 17 (Starsky)
