Just came across this gem ...
... I had no idea that Givenchy patterns were available through McCalls. So Audrey Hepburn! Of course, Givenchy became synonymous with Audrey's style. I don't think it's a coincidence that the model on the pattern packet is an "Audrey type".
This dress reminds me of Audrey's wedding attire in the final scene of Funny Face (1955).
Very young, fresh and simple.
