First Published: December 29, 2011 12:47 PM EST Credit: WireImage LOS ANGELES, Calif. -- Caption Beyonce hosts the screening of Live at Roseland: The Elements of 4 at the Paris Theatre, NY City, on November 20, 2011There was A LOT of awesome fashion this year. So many red carpets, so many moments. (Lady Gaga arriving to the Grammys in an egg? Pippas scene-stealing backside?) Heres how the best of the best breaks down. BEST AGE DEFYING STYLE WHO: Jennifer Lopez WHY: One hot mama! Super short minis and gravity defying plunging necklines at 42 years old. She has rewritten the rules and redefined how a woman in her forties dresses. In fact, she looks better than half the women her age. I got razzed at work because I would tune into Idol just to see what she would wear, but I love her style. She keeps things interesting. BEST CASUAL STYLE WHO: Jennifer Aniston WHY: She doesnt stray very far from her go-to staples like tank tops, cargo pants, leather jackets and motorcycle boots. You know what? It works. Why mess with perfection? BEST SEXY STYLE WHO: Sofia Vergara WHY: With a body like hers, she cant help but be sexy. But the thing I love about Sofia is that she is never vulgar. She plays up her assets, but doesnt expose too much. Thats a true lady. BEST CLASSIC STYLE WHO: Catherine, Duchess of Cambridge WHY: Even under enormous pressure to look perfect, Kate makes it all look so easy. Elegant and classy no matter if shes wearing high fashion or clothes from the high street, she got off to a stylish start. Yes, her wedding dress was gorgeous. BEST MOMMY-TO-BE STYLE WHO: Beyonce WHY: She still rocks 5-inch heels as well as high end designers like Lanvin, Dolce & Gabbana and Roberto Cavalli. I wish I had her maternity style when I was pregnant! BEST HIP MOMMY STYLE WHO: Gwen Stefani WHY: Ive seen her in action at the playground myselfwearing fierce riding boots and jacketwith her signature red lipstick and not a hair out of place. I love her leather jackets and edgy shoes too. BEST OUTRAGEOUS STYLE WHO: Gaga, of course WHY: No one even comes close to the over-the-top ensembles she comes up with. I give her lots of credit for being extremely creative. BEST NEWCOMER STYLE WHO: Hailee Steinfeld WHY: The True Grit star and Oscar nominee wowed on red carpet after red carpet with her spot-on and age-appropriate style. At just 14, she even became the face of Miu Miu. BEST GUY STYLE WHO: David Beckham WHY: Whether casual cool or red carpet handsome, hes hands down the most suave dresser around.
