A lot of the songs from the Who album Quadrophenia mention fashion (specifically mod):
Cut My Hair--"Zoot suit, white jacket with side vents
Five inches long."
I'm One--"Where do you get
Those blue blue jeans?
Faded patched secret so tight."
I've Had Enough--"My jacket's gonna be cut and slim and checked,
Maybe a touch of seersucker, with an open neck.
I ride a G.S. scooter with my hair cut neat,
Wear my wartime coat in the wind and sleet."
Sea and Sand--"I am the face,
She has to know me,
I'm dressed up better than anyone
Within a mile."
Bell Boy--"Ain't you the guy who used to set the paces
Riding up in front of a hundred faces,
I don't suppose you would remember me,
But I used to follow you back in '63."
Dr. Jimmy--"Messed up my Levis"
And the song Zoot Suit (not sure which album this one was on, still by The Who).
I'll edit when I remember more!
