Kate Middleton is back (to her royal duties) and serving up even more proof that she can look amazing in just about anything. At last night's BBC Sports Personality of the Year awards in London, she took the stage, alongside David Beckham, in a stunning floor-length, forest green Alexander McQueen gown, black Jimmy Choo pumps, and custom diamond and blue topaz Kiki Mcdonough earrings. We'd be lying if we said we weren't also on baby bump watch, but truth be told, we were equally taken with the sheer brilliance of her beautifully cut dress.From the central thigh-high slit and bell-shaped sleeves to the V-neck and trompe l'oeil waistband detail, its chic structure was a thing to behold. Whether you've got something to "hide," or you just happen to love a great green gown, we think strategic tailoring and a lush hue can go a long way. It's all about a looser fit, cut close to the body. Translation: no body-conscious silhouettes necessary to make a statement here. Consider this Kate's holiday gift to all of us — in addition to the royal baby news, of course! Opt for a long, streamlined dress in a darker shade of green, and pair it with elegantly low-key accessories.
