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: Long-sleeve leopard-print dresses

WHO'S WEARING IT: Paris Hilton, Kim Kardashian, Michelle Trachtenberg

HOW TO WEAR IT: Last summer, we spotted colored leopard print in the form of minis, tops and even gowns. This season, it's all about the long-sleeve dress. Winterize the popular piece with black tights and accessories.

Even funny gals like Tina Fey like to get dolled up now and then.

The 30 Rock star visited The Late Show with David Letterman last night and dished all about going glam for next month's Harper's Bazaar.

"They put these long, long hair extensions, that's mostly wig, on me," she said of her cover shoot. "And when they put all the fans on you, the wind machine, the lights and all the gay magic you start thinking like, 'Yeah, I look like this!"

Of course, when the wind stopped, Tina said she returned to her normal "homely" self. But we think she looks pretty fab without the "gay magic." And right on trend, too!

Keep reading to see the comedienne's au courant polka-dot ensemble—and to hear the virginity hilarity that made us forget all about Letterman's sex scandal.   

TREND: Watercolor dresses

WHO'S WEARING IT: Alicia Keys (BCBG Max Azria), Leighton Meester (Louis Vuitton) and Thandie Newton (Matthew Williamson)

HOW TO WEAR IT: Watercolor dresses don't scream cold-weather chic. So winterize them with lots of black—black tights, black pumps, black bag, black jacket, black belt. Just think twice about wearing black socks with black shoes à la Leighton. That's one artistic statement not everyone will understand.

TREND: Embellished pants  

WHO'S WEARING IT: Kate Walsh and Sienna Miller  

HOW TO WEAR IT: Two legs full of sequins are all you need to sparkle. Skip Sienna's Gucci suit and instead pair your blingin' bottoms with solid basics like Kate does. If you don't want to draw too much attention to your backside, layer a tunic or boyfriend blazer over a skinny pair of embellished leggings.

TREND: Various incarnations of London-based designer Christopher Kane's black velvet-trim silk dress.

WHO'S WEARING IT: Freida Pinto, Whitney Port and Diane Kruger

HOW TO WEAR IT: Christopher Kane is the designer of the week with not one but three starlets having worn his distinctive frock recently—plus his TopShop line launches today! Wear the new It dress to a cocktail party with matching booties to complement the edgy design. Accessorize with simple earrings and a small clutch.

Shop the steal below at one-fifteenth (!) the price of the original.

TREND: Tonal polka dots

WHO'S WEARING IT: Heidi Klum & Christina Ricci

HOW TO WEAR IT: Tone-on-tone spotted clothing is less in-your-face than your average colorful polka dot piece. In fact, it looks like a solid from afar! So you can totally get away with, say, pairing a tonal print top with a striped skirt à la Heidi.

TREND: Bandage skirts

WHO'S WEARING IT: Rihanna (Plesasure Doing Business), Hilary Duff (Yigal Azrouël), Ashanti (Hervé Léger)

HOW TO WEAR IT: The skirt is meant to be skintight. So get your buns in shape and don't wear anything too revealing on top! For day, dress it down with an oversize shirt—maybe even add a blazer for a more polished look. At night, tuck in a solid tank, add a sexy pair of heels and strut your stuff.

TREND: Mosaic dress

WHO'S WEARING IT: Marion Cotillard (Elie Saab), Mischa Barton (Matthew Williamson), Rosario Dawson (Dries van Noten)

HOW TO WEAR IT: A multicolored tile pattern like Marion and Mischa's is far more interesting to look at than Rosario's monochromatic version. Keep shoes and accessories simple.

Trend: Khaki

Who's Wearing It: Kristen Bell (3.1 Phillip Lim top, Golden Goose pants), Nicky Hilton (Vena Cava for Gap), Beyoncé (Gucci)

How to Wear It: Don't just cuff an old pair of your boyfriend's khakis from his prep school days—unless you want unflattering, tapered legs like Kristen Bell. Instead, search for nontraditional takes on khaki, like a romper or motorcycle jacket.

There are some awesomely bad '80s trends we can do without, but we totally like how colored leopard is making a comeback! The fun, vivid print reminds us of our youth. Plus, it has been given a modern edge, as showcased by Molly Sims' sequined Marchesa shift, Maggie Gyllenhaal's elegant one-shoulder Lanvin gown and Cameron Diaz's Matthew Williamson top with asymmetrical exposed zipper. 

One caveat: Keep the rest of your outfit tame. Cameron's violet ankle boots? A big no-no!

Shop the the steals 'n' splurges below to get the look—or, for just a hint of flavor, try a vibrant spotted accessory instead.

The cross-body bag is extremely practical: You don't have to worry about it falling off your shoulder when you bend down to tie your kid's shoe. And it does double duty as a necklace if the strap is gold or silver. Just make sure the chain is extralong. Diane Kruger's Chanel hits her body too high for the desired carefree effect.

There are options galore when it comes to this trend. Go au courant with fringe, classic with saddle leather and sporty with nylon. Or shop chic evening options similar to Audrina Patridge's quilted purse and Nicole Richie's hippie hobo in the steals 'n' splurges gallery below!

Whether it's sexy cage shoes, rock star fringe or girlie colorblock dresses, Vanessa Hudgens always stays on top of the latest trends. Her au courant fashion, however, usually comes with a hefty price tag. That's why we've scoured the Web to find ways to get the High School Musical star's look without breaking the bank. One of our choice picks is only $14!
