L'Agence

Sarah Jessica Parker invoked a little of that Carrie Bradshaw spirit with this balanced juxtaposition of polished, albeit laid-back, layers (exotic-printed Level 99 denim ($140) and L'Agence coat included) with the sleekest pair of slingback heels. If it weren't for those little details, this could just have been any other jeans and top ensemble, but when you factor in the standout subtleties, the outfit gained a lot of stylish momentum. To take on a similar brand of city-girl cool, start with a sophisticated foundation. Style a solid-color blouse with fitted jeans, and if you're feeling extra daring, spring for a snakeskin-printed pair like Sarah Jessica's. Then, hone in on that one make-it-or-break-it accent — in this case, a stellar teal-hued slingback heel — and let it be the talking point of your look. We love that this shoe is bright, eye-catching, and chic, but never registers as an over-the-top accessory. In fact, we'd go so far as to say these heels are the reason why SJP's daytime look gets our 9-to-5 (and beyond) approval. Chances are, you've got the essential outfit staples already in your closet, but the slingbacks? See our picks below.

Over the weekend, Beyoncé and husband Jay-Z stepped out for dinner at Gigino Trattoria in NYC, and for the delicious occasion, Beyoncé rocked black leather J Brand pants and black high-top Isabel Marant sneakers. Up top she sported a L'Agence contrast boucle sweater ($200), round sunglasses, and oversize gold hoops that read "Obama." A gold necklace, a few gold rings, and a black and white bag completed the singer's date-night look. Re-create Beyoncé's latest outfit by pairing her exact sweater — or this less expensive contrast sweater from Forever 21 ($23) — with your leather pants and sneakers. Finish off with equally snazzy accessories to perfect Beyoncé's funky-slash-sporty vibe.

There's something about fringe that suggests the wearer wants to have a good time. It's celebratory, à la '20s flappers, or it's boho, taking cues from Western references. Either way, it's totally stylish when done in small doses. Check out our editors' picks of fringe done right.

When you want to look all-out tough, throw on a leather motorcycle jacket. But when you want to look semitough, get the nonleather moto. Olivia Wilde recently donned a gray L'Agence version that has the moto silhouette, fused with the coziness of a wool fabric. There's the option of the denim moto, too, but with the cold weather, I'd stick with knits, wools, and flannels for that extra warm feel. The look is casual, effortless, and won't scare anybody off!
