The end of the year is fast approaching, and between picking a party and planning your outfit, it’s about that time to make a resolution for 2012—one that you actually plan to keep. If you need some inspiration, here’s a list of what your favorite celebs are pledging to do in the New Year.

British designer, Richard Nicoll, launched his namesake label in 2005 after graduating from Central Saint Martins and apprenticing under Marc Jacobs at Louis Vuitton. The Australian expat has a knack for sophisticated, wearable, and often colorful designs, which have found him a well-devoted fan base of modern women. We chat with the London fashion week favorite about everything from childhood bike rides to breezing through that dense Steve Jobs biography.

Fendi's Stroller

Babies are living life in the fast lane thanks to an onslaught of miniature collections released this month. And it’s about to get a whole lot better: WWD has reported that Fendi just signed a deal with chic Italian children’s manufacturer Inglesina. The partnership will include a line of strollers, prams, and baby carriers, all bearing the Italian brand’s “F” logo. Rather than going with the traditional pink and blue colorways, Fendi’s baby products will come in the far more sophisticated shades of cream, mahogany, and blue. The carriers are yet another score for the under-10 set, following Lanvin’s childrens’ launch that includes over 20 spring ’12 pieces for pint-sized girly girls. In addition, just last week it was announced that Oscar de la Renta is about to design pieces for (highly discerning) stylish munchkins. And let’s not forget the Stella McCartney for Gap Kids collection, which had fans like Carla Bruni squeezing into the British designer’s pint-size military jackets and printed dresses. Kids these days, they’re just on a roll.

Real men wear pink, and in Chris Benz’s case it’s suitable for everyday. The rosy-haired Seattle native moved to New York to attend Parsons and started his own label after stints at Marc Jacobs and J.Crew. The CFDA Emerging Designer Award winner has a rabid affinity for juice cleanses (they must come in handy this time of year) and is sentimental for sketchbooks. Here he breaks it down for ELLE, one question at a time.

In just a few short years, Charlotte Ronson has become a fashion megastar. In October, The New York Times, sang her praises, labeling the designer as “the girl with the golden touch,” and “one of the most successful retail entrepreneurs of her generation.” In the spirit of the holiday season, we’ve asked Ronson about her famous family, elephants in New York, the sensation of falling in your dreams, and why above all, family trumps everything (and maybe her little dog Oliver too).

Forbes just published its first ever 30 Under 30 list. In its entirety, it actually honors 360 individuals under the age of 30 who, they write, answer the following questions: “Who is reinventing the world? Who should you hire today? Who will you be working for in 20 years? Who, in short, under the age of 30, matters?” The nearly 400 names are split into categories like energy, music, media, food and wine, science, real estate, and art and design. The latter, of course, is stuffed full of fashion names. Joseph Altuzarra leads the pack; they even call him “fashion’s next Marc Jacobs.” He’s joined by the 25-year-old Olsen twins and Alexander Wang—both of whom have created mini-empires at ridiculously young ages. From there it gets more surprising. Pamela Love’s earned a spot on the list, as well as Molly Yestadt, of Yestadt millinery. Their names were chosen by a team of Forbes reporters and narrowed down by three judges: Chuck Close, Jeffrey Deitch and Simon Doonan. If you’d sat on the judging panel, who would you have chosen?

2012 is looking to be a good year for Gisele Bundchen: Her “dream mansion” in Los Angeles is nearly complete, her husband has secured the New England Patriots a place in the NFL playoffs, and now she’s nabbed not one, but three major spring campaigns. In addition to starring in ads for both Versace and Givenchy, the Brazilian bombshell’s turn for Salvatore Ferragamo’s spring ’12 collection just leaked. It’s another beachside shot, although this one trades Givenchy’s all-black ensemble and goth surfboard for a tropical-print silk dress and a palm tree. Meanwhile, Bundchen’s Givenchy colleague Mariacarla Boscono, who posed in the spring ’12 ads with Chris Moore and Simone Nobili, is another multi-campaign threat; her latest is a solo series for Yves Saint Laurent. For these photos, shot by David Sims (a break from Inez van Lamsweerde and Vinoodh Matadin, who had shot YSL for nine seasons straight), the Italian model is working ultra-arched eyebrows and a haircut that we can only describe as a high-fashion version of the Lisbeth Salander. Diane Kendal and Guido Palau get credit for the makeup and hair, respectively, but it seems that Dragon Tattoo mania has swept even the fashion houses. If both Bundchen and Boscono are busy next season, may we suggest Rooney Mara?

Though the world has a new future Queen to look to for fashion fantasies, it’s hard to forget Princess Diana’s emblematic style. Her gowns continue to fetch high prices at auction, and now five of them will be on public display at Kensington Palace. Beginning March 26th, the palace will host a handful of the late royal’s most memorable fashion moments—from a fuchsia silk dress by Catherine Walker to a black shift designed by Gianni Versace. Also included in the line-up is a controversial strapless black taffeta gown by Emanuel that received criticism in the 80′s for its dark color and revealing neckline. How times have changed, as Duchess Kate wore something quite similar to a military ball over the weekend—garnering rave reviews for her bold, uncharacteristically sexy choice (courtesy of Alexander McQueen). The exhibit will be creatively titled, ‘Diana,’ and it’s part of a celebration for Kensington Palace’s $19 million renovation, just the start of a giant year for the royal family. 2012 will also mark Queen Elizabeth’s Diamond Jubilee and the London Olympics, of which Duchess Kate is an ambassador, so there’s much more regal fashion to come!

Bottega Veneta may not rank highly in the minds of animal lovers, seeing that their spring 2012 collection alone featured glazed crocodile, grommet-covered ostrich, and lizard skin accessories. But their standing with tree-huggers just went up. The luxury brand’s Milan headquarters was recently awarded a “Carbon Neutral 2010” certification. It’s apparently just the beginning for Bottega though. The brand is planning to reduce greenhouse gas emissions during their fashion week and sales campaigns—times of the year when pollution spikes, according to the brand. No surprise, considering the amount of power, energy, and air travel that goes into producing a single show. Luckily they’re already moving in the right direction by using carbon credits to offset additional impact. Bottega isn’t the first luxury label to go green, though. Stand-out predecessors include Stella McCartney and Vivienne Westwood who takes part in the International Trade Centre’s ethical fashion program. Maria Cornejo‘s also on board—she used fabric made of recycled cassette tapes in her pre-fall collection. All in all, this is certainly a spring trend that we can get behind.
