Blondes of classic rock/pop. (Obviously most of these are when they were in their prime; in many cases you may not want to look up what they look like today ). It's not only their natural beauty, but what I find particularly attractive is that they all have actual artistic talent.
Debbie Harry, lead singer of the (actually American) band Blondie:
Singer/songwriter Marianne Faithfull, who in her prime was an absolute stunner:
German model Christa Päffgen (known professionally as "Nico") who sang lead vocals on a bunch of stuff, most notably on the debut album of the Velvet Underground (which is excellent, by the way)
Stevie Nicks, co-lead singer and songwriter of the band Fleetwood Mac. I think she was more stylish than actually "beautiful," but should be here nonetheless:
Michelle Phillips, co-lead singer of the band The Mamas and the Papas. Not only a talented vocalist but from everything I've read, she seemed fun (in a somewhat slutty way). A bit of a stretch since she was a brunette most of the time, but fuck it, I'll add her here:
There may be a part 2 to this post, but for now I gotto go work.
