TREND: Foliage-inspired fashion

WHO'S WEARING IT: Nicole Richie, Joss Stone and Kerry Washington

HOW TO WEAR IT: Fall is the perfect time to branch out with an homage to the lovely leaf. Frond-shaped earrings are a really easy way to incorporate this perennial earthy trend into your everyday look. If you're shopping for a leaf-printed dress, we suggest you opt for one with seasonally appropriate long sleeves. The stars in sunny SoCal might be comfortable with bare arms in autumn, but not everyone can be so lucky. Brrr!

TREND: Crystal-encrusted tops

WHO'S WEARING IT: Eva Mendes and Chloë Sevigny, both in Miu Miu looks from the spring runway

HOW TO WEAR IT: Diamonds aren't every girl's best friend. If you hate digging through your jewelry box, try an embellished top instead. At last night's MOCA 30th Anniversary gala, stars shined in intricately bejeweled designs that required no jewelry except for a ring or simple pair of studs. Just stick to one crystal-studded item per outfit. Head-to-toe gemstones only worked on Miuccia Prada's fall runway.

TREND: Cap-toed pumps

WHO'S WEARING IT: Blake Lively, Tyra Banks and Charlize Theron

HOW TO WEAR IT: The classic pump gets a fresh update with just a dip of contrasting color at the toe. Follow in Tyra's and Charlize's fashionable footsteps and show off the statement shoes in a cocktail dress with a high hemline. Otherwise, they'll get lost underneath your frock's fabric (ahem, Blake).

TREND: Patterned trench coats

WHO'S WEARING IT: Selena Gomez, Willa Holland and America Ferrera

HOW TO WEAR IT: Forget boring beige. This fall, the timeless trench gets a fresh makeover with eye-catching patterns, like houndstooth and tonal polka dots. Wear the printed coat with something simple and chic underneath—think sweaterdress, tights and knee-high boots. Also, make sure the hem of your skirt or dress doesn't go past the length of the jacket to ensure a tailored look.

TREND: Dresses with a single bow accent at the waist

WHO’S WEARING IT: Emily Blunt (Dolce & Gabbana), Zooey Deschanel (Luella) and Eva Mendes (Christian Dior)

HOW TO WEAR IT: A sophisticated frock wrapped in a sweet bow has "holiday party" written all over it. But for the gift that keeps on giving, we suggest investing in a classic black bow belt to get the look. That way, you can add a hint of girlie charm to any dress. Add a pair of black tights for a totally winterized outfit.

TREND: Tweed

WHO'S WEARING IT: Sienna Miller (Rag & Bone), Jessica Biel, Blake Lively (Smythe)

HOW TO WEAR IT: Tweed brings a fall element to any outfit. Just look at Sienna's shorts! While similar ones are available, we prefer the sleekness of Jessica's pencil skirt. And we love how Blake made her boyfriend blazer edgy with leather pants. Since the material never goes out of style, it's OK to splurge on a coat or classic pair of pants.

TREND: Black and white striped dresses

WHO’S WEARING IT: Kim Kardashian, Milla Jovovich & Hilary Duff

HOW TO WEAR IT: The contrasting hues are so striking and chic, it's no wonder they're such a hit with celebs. Since horizontal stripes can be unflattering on most body types, make sure you belt your waist. Otherwise, diagonal or vertical stripes are the way to go! Halloween tip: We're going to pair our striped frock with black over-the-knee boots for a sexy jailbird costume!

TREND: Blue print dresses

WHO'S WEARING IT: Diane Kruger (Balenciaga), Kristen Bell (Oscar de la Renta), Ali Larter

HOW TO WEAR IT: Look for blue prints that have black in them. That way, you can winterize the look by adding tights, booties and a leather bomber jacket when it gets cold. Since the print is the main focus, you want to keep accessories to a minimum. A simple necklace or earrings will do.

WHO'S WEARING IT: Beyoncé and Alexis Bledel

HOW TO WEAR IT: From ruffled zippers and rosettes to croc print and fur, a textured skirt will give your look some visual interest. Just be sure to tuck a nonfussy top into the bottom—you don't need any more added volume on your figure. Wear simple yet sexy heels to elongate your gams.
