While Grace of Monaco, the biopic of Grace Kelly starring Nicole Kidman, won't make its world premiere until the Cannes Film Festival in May, a new UK trailer that debuted online on March 6 gives an in-depth look at the film. More importantly, we get to see oodles of the mouth-watering costumes for the late Hollywood actress-turned-princess.

Here, a look at some of the best outfits from the new film, which is set in 1962 (six years after Kelly and Prince Rainier of Monaco's "wedding of the century").

Kelly, seen here in all of her Hollywood royalty glamour in a strapless gown with full skirt, was known for her love of Cartier jewelry and was frequently spotted in their baubles. The esteemed jewelry house worked with director Olivier Dahan to recreate the monarch's favorite jewels, including her 10.47 carat emerald-cut diamond engagement ring and other frequently worn pieces like the three-strand diamond necklace and ruby and diamond tiara.

While we didn't spot the royal movie star's go-to Hermes bag (which was renamed "Kelly" in her honor), many of her dresses, including this gold gown, feature her trademark style of a fitted waist and high neckline.

What would a film set in the 1960s be without a fabulous hat? Kelly wears a structured black hat with a cherry red outfit, black gloves, and red lipstick.
