Here is the beautiful Liz Taylor in the famous "Cat" dress designed by Helen Rose for Taylor's role in Cat on a Hot Tin Roof (1958). The dress was made of white silk chiffon and showed off Liz's beautiful shoulders. It was a relatively short cocktail dress and the Grecian style draping at the decolletage was expertly fitted. It was made in the MGM Wardrobe department by Inez Schroedt, who had been working there since Adrian's time. Helen Rose had so much demand to recreate the dress that she began her own line based on this dress. Needless to say, it was knocked off at cheaper price points. Both Helen Rose and Edith Head designed many of Liz Taylor's gowns for both movie roles and special occasions. They usually capitalized on Liz Taylor's generous cleavage, especially as the censors loosened up a bit (but not completely) in the late 50s and early 60s movies.
This lovely photo of Grace Kelly is from Rear Window (1954). It's a beautiful gown with a black bodice and a very full white chiffon skirt with beads designed by Edith Head. Grace wears several stunning gowns, dresses, and even a negligee that would wake the dead, but somehow go unnoticed by Jimmy Stewart. But they're wonderful to look at again and again in the movie. Miss Head won eight Oscars for costume design, but ironically, none for To Catch a Thief, her most deserving costume ensemble in my opinion. The costumes are not only wonderful designs in themselves, but perfect for the plot and perfect for Grace.
Here is a lovely all-black chiffon evening gown costume sketch designed for Polly Bergin by Edith Head for the movie That's My Boy (1951). This was a Dean Martin Jerry Lewis movie, but even for a comedy, ladies like Polly Bergin were dressed to be glamorous. And so were the sketches.
All three of the dresses and gowns shown are timelessly in fashion. They all used a silhouette that accented the female body while providing additional visual stimulation from a beautifully worked fabric. What's more, for the movies they helped create character.
