>>108177116The 90s resulted in a lot of ridiculous outfits meant to look cool, but the 00s is when they tried to make them all look tacticool and get rid of anything that looked too flamboyant or ridiculous.
Tbh Piper kinda represents the change pretty well despite having minimal costume changes.
Intro (1960s) to COIE (1985) he wore a tunic that looked like a minidress with tights.
Late 80s he was given thigh highs, an open shirt that still was supposed to be a tunic, but added the cloak.
He actually stopped appearing in that for a few years in Waid’s run and appeared in civvies since he doesn’t have a secret identity and helped Wally that way.
Then late 90s hit and got pants, silver shin guards, and silver shoulder pads.
Then in 00s Kolins straight up said he thought Piper looked ridiculous and didn’t like him because of that, so Johns redesigned him to look cooler, hence the black/dark green body suit, weird harness, and ratty cloak.
