A Place in the Sun is a film reflecting changing times in the 1950s. Starring two great screen beauties, Elizabeth Taylor and Montgomery Clift in essence is struggle of money and class portraying Clift as someone on the up and torn between his place and that of debutante Angela (played by Taylor). It is quite a gruesome story in terms of Clift's character and actions.
The real significance in terms of costume is the dress Taylor wore in the pool room scene - a strapless boned bodice top with an enormous white tulle skirt over a pale green satin and white violets covering the bust. Edith Head won the Oscar for best costume in the black and white film category and the dress captured the public imagination so much so that every prom had many an Elizabeth Taylor. In fact one could argue that this dress defined a look for proms and brides ever since 1951.
