All recent papers from 1950 high fashion made me think of my first exposure to this form of dramatic art, for better or for worse has been indelibly: Lucy and Ethel in his burlap sack, bucket hats clothes and food, thinking they were all in the boulevards of Paris. "Jacques Marcel" - the designer who created the dresses believe (actually the good work of Ricky and Fred) - was fictitious, but could have stopped at a number of French designers who were in the time to experiment with clothes waistless.
Cristobal Balenciaga was one of the first - both in the relaxation of the adjustment in the back (inspired by the original "sacques" backed loose dresses that were ubiquitous in the 18th century), and the lengthening of a jacket to in long robes.
Others followed suit with a more fitting, the dress, but it remains essentially waistless. Writer Anita Loos enthusiastically in Vogue magazine about his seductive mystique: "Not a gentleman is never going to puzzle their brains about how a girl in bikini bathing suit."
If it is up to the antics of Lucy and Ethel, or due to the classical expression "that would look good in a sack of potatoes" (shown excellent Marilyn left), Americans have always had a caring relationship with the dress sack. I wonder if that extends to other nationalities as well, I'm pretty sure that people all over the world, despite the guarantees of vintage Vogue magazine, tacitly prefer bikinis.
