With so many glamorous events leading up to the Queen's Diamond Jubilee and a bevy of award dinners and red-carpet galas, the UK may just have been the epicenter of chic this week.

In London, Natalia Vodianova hosted the NSPCC Pop Art Ball, where a gaggle of well-heeled guests — including Agyness Deyn and Naomi Watts — wore (what else?) ensembles by cohost Stella McCartney. Also in London, Glamour's Women of the Year Awards brought an array of good looks, with Lily Collins's strapless emerald Alexander McQueen looking especially enchanting.

Laura Bailey and Erin O'Connor (left) proved their model merit over in Epsom, England, at the Investec Derby Festival: both were equally stunning in their respective — and elaborate — bespoke fascinators made especially for the occasion. And in Oxford, Donatella Versace made her mark wearing glossy black Versace while giving a talk at the Oxford Student Union.

Those looks — plus more from elsewhere in the world, including Ashley and Mary-Kate Olsen in New York and Kate Moss in Barcelona — are here, in our best-of-the-week slideshow.

A recent trip to India inspired Roberto Cavalli's Resort 2013 collection for Just Cavalli, which explains why these garments are covered in leopard print and images of exotic flowers. All of the pieces — from a green-and-white full-length gown to baggy shorts and minidresses — are guided by Cavalli's commitment to hip-hop style, but the patterns like alligator skin and Venus flytrap prints keep the ensembles current and fresh. Cavalli's designs succeed just as well in a full-on color as they do in pure white; a few looks created of all-white pieces allow all of Cavalli's ideas to shine through without distracting from one another.

This may just be the year of the cameo. Not only did Lanvin offer them up in dramatic medallion styles for Pre-Fall 2012, but now Miu Miu's gorgeous crystallized versions for Summer 2012 have finally hit online and in stores.

Though classic techniques like hand engraving and investment casting were used to create these jewels — and they may be adorned with crystals, brass, and pearls — these cameos are anything but old school. Each silhouetted face comes in a statement-making jumbo size and backed in an eye-popping hue — vivid marigold, tomato red, pink, or cerulean blue.

Comme des Garcons designer Rei Kawakubo will be honored with the International award at this Monday's CFDA Awards, and already the industry is getting a head start on celebrating.

Earlier this week, Style.com published a tribute in which notable fashionables — including Taylor Tomasi Hill, Shane Gabier, and Chris Peters — discuss their love for the avant-garde label. Then on Wednesday, Cathy Horyn offered her perspective on Kawakubo's 40-plus-year career. "No living designer, with the exception of Azzedine Alaïa, is held in higher esteem by her peers, and none has enriched our spirit in so many original and confounding ways," Horyn wrote. In an attempt to shed light on Kawakubo's creative process, Horyn also reprinted an email from the designer, an excerpt of which is below:

"My design process never starts or finishes. I am always hoping to find something through the mere act of living my daily life. I do not work from a desk, and do not have an exact starting point for any collection. There is never a mood board, I do not go through fabric swatches, I do not sketch, there is no eureka moment, there is no end to the search for something new. As I live my normal life, I hope to find something that click starts a thought, and then something totally unrelated would arise, and then maybe a third unconnected element would come from nowhere. Often in each collection, there are three or so seeds of things that come together accidentally to form what appears to everyone else as a final product, but for me it is never ending. There is never a moment when I think, 'this is working, this is clear.' If for one second I think something is finished, the next thing would be impossible to do."

Kawakubo will not be in New York to accept her award Monday, but she has asked her longtime friend filmmaker John Waters to present and accept the award on her behalf. In the slideshow, a look back at some of our favorite looks from recent Comme des Garcons collections.

If comedy is the opposite of being ladylike, then Alice Temperley's Resort 2013 collection is as serious as it gets. Temperley took her inspiration from enduring beauties like Sophia Loren and the style of women in the South of France in the '50s and '60s. The result is a restrained collection of demure classics. Dresses in bright red, cream, black, and blue jewel tones are nipped in at the waist in a nod to the New Look and are accented with grosgain ribbon and starfish brooches. The evening gowns in the collection show off a little leg with an emphasis on soft draping. But a masculine white suit — featuring a double-breasted jacket with wide-leg pants — is perhaps the garment that best summarizes this collection's traditional bent: cool, classic, and timeless.
