Very nice list. Huge thumbs up for Led Zepplin and The Beatles. However there are many bands out there that have great fashion sense. Here's a few I feel were overlooked.
Captain Beefheart and His Magic Band
The Captain had such exquisite taste in fashion. The same goes for his band mates.
Black Sabbath
The godfathers of Metal in their dark fashionable glory!
Rush
Love their taste in clothing for the 1970s!
Judas Priest
These guys, Rob Halford in particular, are the ones solely responsible for creating the metal look. It was them that inspired millions of metal heads like myself to garner black leather and studded accessories.
