It’s not specifically about clothes, but Body Count’s “Cop Killer” begins with a description of Ice-T’s fashion sense:

Well for one thing, now we can include Dan & Dan’s “Requiem for a Wardrobe” from 2008! 
We can also add this song by Leningrad about Louboutin shoes.

She wore blue velvet

And” twice.

so let me ho-oo-ooo-old, both your hands in the holes of my sweater”
Didn’t remember that. I saw a production (in I want to say – 1985?), but I learned it first as a half-hour cantata in 1973.
Rodeo champ and country singer Chris LeDoux had a couple of songs about old cowboy hats, including “This Cowboy’s Hat” (1991) and “Under This Old Hat” (1993).
