Pierre Cardin is a member of fashion's Hall of Fame and a man that has left the fashion world a big legacy. I'm pretty sure everyone is more or less familiar with him, and even owns at least something with his name (not to be forgotten the fact that he was the first designer to license many things bearing his name, including mass ready to wear). While his designs were mostly for women, during the mid 60s (circa 1964-1967) he was one of the precursors of "Space Fashion".
Below a classic photo that depicts some of his "galactic" designs. Call them reminiscent of Star Trek or whatever, they're something I'd like to wear one day (of course not with that very "galactic" vibe), and they're so basic imo. My favorite ones are the purple pants with leather jacket one, the green one, and the brown one in the back (practically all).
You can see on the left side of this photo a classic English gentleman, looking closely and in awe at this Space Mod crowd. Definetly shows the breakthrough Mod culture and fashion had at that time in a very classic and traditional world.
