Somehow when I was a very little boy, my parents sometimes put me on a Braniff flight to go see my grandparents. Of course I had no concept of "sexy" but I remember really liking the super colorful environment and clothes the staff wore.
About 10 years ago PARCO (a department store chain here in Japan) did a Braniff International design retrospective exhibit with all sorts of corporate stuff and uniforms from the era. Also in 2012 there were the Braniff Converse shoes here in Japan. I got the orange high tops.
