This photo must have been taken around the time of glam/hair metal's peak, when the more the dudes in the band looked like chicks, the more popular they were. And even if the band wasn't popular, they could, for a brief time at least, get away with looking completely androgynous. It was a relatively short window of time, though, and inevitably bands had to outdo each other, leading to these kinds of shenanigans. (Thank god grunge eventually put a stop to the escalating ridiculousness.)
An interesting side note about these gals is that they had the same exact band name as a much more influential (though not necessarily popular or well-known) band from the early '80s. As far as I know, there was never a dispute over the name.
As far as I'm concerned, there's no shame in actually knowing what band this is, but if you'd prefer to post a reply anonymously, that's cool with me. I understand.
Update: Well, I was starting to think that I had stumped everyone with the last few posts, but Keir correctly guessed that this is indeed Sweet Savage from Dallas, Texas. For a good laugh, I'd suggest checking out the ridiculously longwinded bio on their MySpace page. By their own account they were "this close" to being megastars. If only...
