Im in the same boat as I shaved my head in march and recently had it cut so it's now in a sort of pixie cut - I had in my head that if I could wait it out all my hair would be 4 inches long and them BAM! middy haha but I could not get past the mullet so I cut it. I went for a Jean Seberg type style but longer on the top so I can wear bangs (which I curl) if I want to or else pin it back if I feel like it. So in that way I can grow out the top so when the bottom grows out it will go into a bob and not have the dreaded mullet. I find if you can get it long enough to put some curl into it with a curling iron then you can do a sort of 20s/30s styles relatively easily and get some just wild frizz going which hides the uneven-ness of the back, especially if you do use a ribbon or scarf to hide it. I know you asked for 50s but i think as you see in the pictures of Liz Taylor etc. that kind of bouncy curl can be quite 50s too.
