When Grace Kelly married Prince Ranier III of Monaco in 1956 she wore a white lace dress designed by Helen Rose, MGM’s award winning costume designer. Rose, and a team of thirty-six seamstresses, spent six weeks on the gown. Sarah Burton’s spent months on Catherine Middleton’s white lace gown—and given the secrecy under which she had to work we imagine Burton employed far less people. The results are startlingly similar, down to their bouquets, tiaras and veils. So in case you end up marrying a prince, take note: lace sleeves are a royal must!

On The Today Show Matt Lauer called out the glowing and pregnant Kate Hudson on the rock on her ring finger. When he asked if it was an engagement ring, Kate said, ”I’m so glad you noticed—I kinda felt like the announcing thing feels so silly; I was just waiting for someone to notice.” Apparently she had been engaged for the past week. Paparazzi, you guys need to step up your game! When pressed for details on how the Muse frontman popped the question, she merely described it as “very sweet; it was very romantic. He [Matt] is a beautiful man; I’m excited.” With a new man, a new baby and a collaboration with Chrome Hearts, Kate Hudson is a very lucky girl. Congrats and best wishes you two.

When St. John replaced Angelina Jolie with a string of models, most notably Karen Elson, they made it clear they were going in search of their roots. They’d gotten lost along the way, chasing the youth factor, hiring an actress instead of Kelly Gray to be their face and re-working their stable of classics.

But now it appears as if they’ve steadied, and they’re jumping back on the A-list bandwagon. It makes sense that the first face of the new St. John would be Kate Winslet. Winslet’s one of the few A-list actors who feels accessible—everyone loves her even though she’s gorgeous, wealthy and ridiculously talented. She’ll appeal to the classic St. John customer as well as a younger crowd, and the other brand she reps, Lancome, is perfectly aligned with St. John. WWD reports they’re shooting the fall ads in New Jersey, with Craig McDean, today.

Mandy Moore spent Monday with the United Nations Foundation celebraing World Malaria Day. In the morning, Moore—an ambassador for PSI, a global health organization whose programs target malaria and other health problems—and former Houston Rockets center Dikembe Mutombo unveiled a new public service announcement on the Toshiba Vision screen in Times Square to highlight “Nothing but Nets,” the foundation’s grassroots campaign to raise funds for and awareness of insecticide-treated nets that prevent malaria-carrying mosquitoes from biting at night. In the evening, Moore, Mutombo and other “champions” in the fight against malaria were honored at a reception at the UN, where the champions’ portraits—by celebrity photographer Platon—went on display. Both the PSA and photo exhibit run through late May.  We caught up with Moore at the reception to talk about her volunteer work, music and fashion choices.

Mother’s Day is coming up, and it’s our daughterly duty to let the superwoman in our lives know how much she is appreciated. Give mom a call, take her out to brunch, or pick up a little decadent gift that she would never buy herself. But whatever you do, make sure to give her a loving thank you. Check out a few things on our list!

Think In a recent article, The New York Times explores the newest explosion of vanity sizing (the adjusting of measurement scales so that a woman who once wore a size 10 can now, arbitrarily, wear a size 8) and its footprints on the American retail scene.  MyBestFit, a full-body-scanner that calculates the circumference of your various appendages, can now specify what clothes to grab according to the brand you’ll be buying, cutting back on time, energy, and supposed humiliation. While the issue of rotating between a small, medium and large can be perplexing in a mall, it’s exponentially more frustrating for online shoppers, who often need to order (and thus return) multiple items at a time in order to discover their true size. As the author explains, ”Take a woman with a 27-inch waist. In Marc Jacobs’ high-end line, she is between an 8 and a 10. At Chico’s, she is a triple zero. And that does not consider whether the garment fits in the hips and bust. (Let’s not get into length; there is a reason most neighborhood dry cleaners also offer tailoring.)”

Originally published in 1965, the recently reprinted photography book Take Ivy documents a global fascination with the seemingly mundane topic of American prep style. While the clean-cut looks throughout its pages resist the stinging label of “old-fashioned,” turning to the fall 2011 runways as a cross-reference proves that we have made progress since. The collections of ADAM, Yigal Azrouël, and Tommy Hilfiger are anything but traditional, infusing East Coast refinement with grunge, glam and everything else that would make Lily Pulitzer’s skin crawl. As Pete Seeger sang in “Little Boxes,” “The kids go to the university.” But now, they slap on some leather, a little neon, and certainly don’t, “all come out the same”, updating their tweed and argyle for the 21st-century. As the admissions decisions roll in, here’s how to create your all-American look based on the recent trends, and redefine prep just in time for enrollment.

Reese Witherspoon’s onscreen personas often portray a strong sartorial statement, from Election’s no-nonsense chic to Legally Blonde‘s overt femininity. But that doesn’t mean Witherspoon lacks a voice of her own on the red carpet. She regularly demonstrates her confidence and fashion savvy with handpicked vintage finds, such as her infamous 1956 Dior from Didier Ludot’s Parisian shop and the most red-hot labels of today, like Jason Wu and Nina Ricci. See our favorite highlights of her style evolution after the jump:
