That's what I get for not hosting it myself. Here.
And yes, I liked a lot of the 70s Legion uniforms. Which, I think, were Cockrum's designs, not Grell's? A few from before too--Brainy's has something perfect, basic and solid in its retro plainness that always makes it look wrong when changed, and Shadow Lass has mostly just pared it down.
Some were horrible: Cosmic Boy. Who, like many others, did get a decent redesign from Giffen.
Some, like this or Shrinking Violet, I never understood why they changed, except that Vi's might be hard to draw with all its designs and stuff. Some were so good they survived mostly unchanged since the 70s--Star Boy, Lightning Lad, Dream Girl, and my personal all-time favorite Phantom Girl. I'm sorry, Y'ALL call me whatever you want, but growing up, a big appeal of the 70s Legion was how much skin you saw in that book by comparison to other comics. Seriously, I think only the fantasy comics like Star*Reach went further. (Jim Starlin's WARLOCK would be another, and Starlin did work on the Legion, that two-parter where Brainy went mad, which I found recently and might post)
One of my only exceptions in my war on pink would be Saturn Girl's uniform at the time, probably the scantiest possible female costume in the 70s. And just about the only time any attempt was made to make her sexy--mostly otherwise she's depicted as something of an ice queen, or these days, a bit of a geek. Which is probably the better take, but I did like thee costume.
But hell, in that stuff even Infectious Lass, god help us all, looked sexy.
