Not a clue-I'll toss in Ethel Kennedy as a Hail Mary pass.
Looks like Barbara Howar.
It looks a little like Vera Miles c. 1973, but I don't think she would have worn a harlequin unitard in public.
Helen Gurley Brown?
the Pricess Radziwill?
*takes harlequin print as clue*Emmett Kelly Jr. in drag?
Tippy Hedron? Cloris Leachman?
On second thought, Helen O'Connell
Helen Gurley Brown or Natalie Wood in really good Helen Gurley Brown make up on break from filming Se and the Single Girl.
Phyllis Diller .....
i love the barbara howar guess.
She's too chunky for Helen Gurley Brown; I go with Barbara Howar too.
It's Gail Patrick!
