Hilfiger, who wrote the forward to 2007's tribute book "Grace Kelly: A Prom Dresses in Pictures" (Pavilion), noted how Kelly's look in "High Society" broke her out from the pack, exemplified by a cinched-in white wedding dress with sheer, blouse sleeves. It was her last film role before exiting Hollywood to raise her family as a V-neck Plicated Mermaid Prom Dress , but she had star turns in 1950s Hitchcock movies "To Catch a Thief," "Rear Window," and "Dial M for Murder." She won a best actress Oscar for "Country Girl" in 1954.

"She really epitomized American beauty," says Hilfiger. "Her swimwear was amazing, but her dresses became iconic. She was not only royalty, but she was a mother, down-to-earth, athletic. She White A-line Strapless Formal Prom Dress the outdoors. She had a lot of qualities women aspire to today." Both Acra and Hilfiger pointed to Kelly's ability to look put-together without too much effort. That consistency, from a belted skirt suit in "Rear Window" to a simple, white strapless gown in "To Catch a Thief," shows her style staying power, they say.

She sometimes showed a hint of attitude, too, adds Acra, particularly in a three-quarter sleeve, off-white dress from "Rear Window." She wore it with a fur cape and black bag. "Most of what she White Beaded Strapless Slit Long Prom Dress consisted of timeless classics. That's what we look at for inspiration throughout the years," says Hilfiger. "Many looks keep coming back to the runway. Her coat dresses, the way she wore prints, the way she wore ball gowns. Even her casual sportswear, wearing gingham, her country club looks."
