Teenagers love taking fashion risks. Sometimes it works (doesn’t Selena Gomez always look adorable?), and sometimes it doesn’t (remember fashion bomb Mischa Barton?).  Here are just a few examples of what NOT to wear when you’re a teen model, musician, actress or celebrity of any kind:

Taylor Momsen

When she’s not playing Jenny Humphrey on Gossip Girl, Taylor Momsen is trying way too hard to look like she doesn’t care about fashion.

The young woman needs a personal stylist… pronto.

Rihanna

Pop superstar Rihanna’s sleeveless top is funky. Her lipstick is gorgeous. The colossal matching sunglasses are fine.

The Kate Gosselin hair (on anyone, ever) is not.

Miley Cyrus

Yahoo’s OMG fashion critics compared Miley’s nasty dress to her famous father’s infamous mullet.

The fishnet stockings and a come-hither pout don’t fool us Miley, you still look like you’re 12.

Emma Stone

The Ghosts of Girlfriends Past actress appears to be channeling an angelic version of Wednesday Addams. The material and design are matronly, and the color blends right in with Emma’s pale skin.

The unnecessary bow around her neck is the only “blue ribbon” she’ll win with this ensemble.

Our kids worry about how they look for school, the mall, the football game… not the red carpet. That’s why my picks for the best-dressed teen celebrities is based on what the stars look like when they’re not modeling for the paparazzi.

#5 Chace Crawford
It’s probably unfair to put Chace Crawford on a best-dressed list. With a face and physique like his, Chace would look chic in a paper bag.

But the Gossip Girl star really does look his best when he’s not filming. Whether he’s wearing a white T-shirt or a Yankees ball cap, Chace drives the girls crazy.

Who else would rock a pair of Diesel Revick 88Z jeans (left) like Chace?

#4 Minka Kelly
Is it possible that Minka inherited her fashion sense from her parents? Doubt it — Dad’s an Aerosmith guitarist, and Mom’s a former Vegas showgirl.

The Friday Night Lights beauty always looks amazing.

Here (left) Minka struts her stuff in a pair of Hudson Signature bootcut jeans. Wow. And her furry friend makes the perfect accessory!

#3 Zac Efron
Zac once said that he’s “an actor who can sing a little bit.” But after his performances in High School Musical and Hairspray, it appears he can do both… and more.

What’s not to like about Zac? He’s talented, handsome, devoted to his girlfriend, has great hair, and always looks fab.

This (left) is how he dresses to get a bite to eat at Hugo’s Restaurant.

#2 Demi Lovato
Disney’s newest rising star is Demi Lovato. The star of Camp Rock, Princess Protection Program, and Sonny with a Chance is also a rising star on the fashion front.

Demi likes to take risks trying anything from neon pink lipstick to gothic chains and studs.

Her unique style really shines here (left) in this IRO Vardith cotton vest paired with ripped jeans and strappy black boots.

It’ll be interesting to see how Demi transitions from funky teen to young adult.

#1 Leighton Meester
Gossip Girl Blair Waldorf has access to the finest fashions. Sometimes it’s tough to tell if Leighton Meester, who plays Blair, is wearing her own duds or something from the show.

Leighton has superb taste. Here she is (left) out on the town in Phi zip black leather pants and a Proenza Schouler Resort 2010 bag.

Leighton has the best fashion instincts (or maybe the best stylist?) in Tinsel Town.

“Show the Twins”
“Female Students Wanted for Sexual Research”
“Female Streaking Encouraged”

You’ll find these lovely sentiments on the New College line of  T-shirts from Abercrombie & Fitch. The American Family Association (AFA) is not happy.

In a recent email press release, AFA president Tim Wildmon stated, “Abercrombie & Fitch does not merely sell a popular line of clothing, they sell a lifestyle. And because A&F clothing is popular among teens and college kids, the influence of their sex-as-recreation lifestyle is widespread.” According to the AFA, younger teens and pre-teens are also a target of the retailer’s “sexualized shirts” and “pornographic-themed material.”

The AFA is right. Abercrombie & Fitch knows darned well that kids, tweens and young teens covet the clothes their elder role models wear, and A&F clothing is well represented in pop culture. Characters from The O.C., The Gilmore Girls, One Tree Hill and the blockbuster movie Twilight wear A&F apparel. The actors who play our favorite roles — Jennifer Anniston, Chace Crawford, Alexis Bledel, Nikki Reed — wear A&F in real life, too.

But beyond the whole “sex-as-recreation” argument is the fact that these T-shirts are just downright sexist.

Parents:  Will you patronize this company whose “messages” degrade young women?

The latest trend in outwear is the motorcycle jacket. We’re not talking Harley Davidson biker chic (although that’s pretty cool, too).

We like the motorcycle jacket — in fabulous new colors and fabrics — paired with just about everything.

We’ve rounded up some of our favorite, most stylish celebrities for a fashion show of this contemporary and versatile piece.

Black Leather…
The classic black, leather motorcycle jacket is exactly what we expect to see on Kristen Stewart. Here, Kristen pairs her jacket with denim cutoff shorts, a simple white tee, funky jewelry and Joan Jett hair. Jacket by PRPS.

Colors…

Beige
Dakota Fanning (left) looks cool and casual in a beige leather motorcycle jacket. She takes an otherwise boring outfit and makes it super hip with this well-fitted piece from Bebe Antique. Even though we’re sometimes not sure if Dakota is a big girl or a young woman, her clothes somehow are always age appropriate.

Gray
Meanwhile, Jessica Stroup (right) is too hot to handle in this H&M faux leather motorcycle jacket. The amazing gray-blue color beautifully complements Jessica’s sexy black mini dress. We can totally picture Jessica’s 90210 character wearing this very jacket.

Brown
Another gorgeous Jessica (Biel, left) wears her biker jacket in brown. With casual jeans and a what could be Justin Timberlake’s scarf, Biel’s William Rast leather motorcycle jacket offers a nice alternative to biker-black. Biel is dressed for shopping, lunching, or just hangin’ around.

Fabrics…

We absolutely love Blake Lively’s contemporary motorcycle jacket. The Alexander Wang piece combines soft denim blue suede, lambskin sleeves and a silk lining.

Not just for girls…

We can always count on American Idol winner and fashion icon Adam Lambert to show us the trends. In his black leather motorcycle jacket from the Monarchy Collection, Lambert is the consummate pop and rock star.

Other celebs spotted in motorcycle jackets include Lindsay Lohan, Kate Moss, Rihanna, Ellen Page, Demi Lovato and Rachel Bilson.

How about you? Do you like your leather black and studded or colorful and soft?

Girls aren’t the only ones wanting to have the latest hairstyles. Guys today spend a ton of money and effort getting just the right look. So, what is the “right look” for back-to-school 2009? Take a cue from some of today’s hottest celebrities:

The hunky “Gossip Girl” star Chace Crawford has THE look. It may seem like he just rolled out of bed, but that carefree look is the product of styling gel, highlights, and the perfect cut. Chace’s long bangs play up his gorgeous baby blue eyes. This style looks best on guys with chiseled facial features. One thing’s for sure… however Chace wears his hair in the upcoming remake of Footloose, it’ll look better than Kevin Bacon’s!

Some guys hate their curly hair, but Jake T. Austin of Disney’s “The Wizards of Waverly Place” knows how to work it. The Hotel for Dogs heartthrob once wore his hair to his shoulders. His new, shorter cut is more grown-up and masculine. Jake wears a side part and lets the curls go where they may. We’ve got our eye on this young man — he’s a “natural” as a little league baseball player in 2009’s The Perfect Game.

Then there’s Taylor Lautner. Sure, we love the long, luscious locks he wears as werewolf Jacob in Twilight and New Moon, but his cropped coif shows off his adorable half boy/half man features so beautifully! Taylor’s hair looks like it could suffer some serious cowlicks, but he’s got things under control with tons of layers. Long hair, short hair — heck, even bald — Taylor looks good.

Some obvious omissions from this post are Robert Pattinson (too wild), David Beckham (too shaved), and Zac Efron (too High School Musical). Tell us which hot Hollywood hunk you think has the best hair.

To some, jeans are jeans — they all look the same. But your kid knows better.

If you have a teenager, you understand that the casual, “I don’t care” look of jeans actually requires a tremendous amount of thought and effort to pull off. Your child has taken into consideration a myriad of factors, including brand, fit, style, and color. Here are some of the trends that may be important to your teen as she goes jeans shopping:

Skinny Jeans
These super-tight jeans are like denim spandex. Not every body will be flattered by the form-fitting silhouette, but it’s great for slender gals like Selena Gomez. The jeans experts at Levi’s provide a lot of different skinny options, including high-rise, low-rise, super-low, and flood jeans. And we’re not just talkin’ blue jeans here… Levi’s skinnies also come in black, white, khaki, coral, shock blue, and neon pink. Prices range from $30 to $200 per pair at Levi’s.com.

Destructed Jeans
Some parents may dislike the idea of spending good money on a pair of pants with holes in them, but ripped jeans continue to be a hot trend. Fashion critics bash celebrities (like Taylor Momsen) who sport this look, but that doesn’t stop them. Though these jeans may convey an “I’m not trying too hard” appearance, there’s a definite art to just wear and how large each rip or tear is. Shop Macy’s for great styles, like Baby Phat Tattered Flared Jeans in Slash Wash, $69, and Hot Topic for Tripp Black Ripped Knee Skinny Denim Pants, $42. Or send your own favorite pair to Destroyed Brand and they’ll put the holes in for you!

Boyfriend Jeans
Katie Holmes started this trend when she was spotted wearing hubby Tom Cruise’s jeans. The boyfriend look is a widespread category of jeans — long or short, dark or light, rolled or cropped, ripped or not. The key to this look? Make sure the jeans look like that belong to someone else — a boyfriend, perhaps? Find this style at Victoria’s Secret, from $40 to $70… or borrow a pair from a guy friend!

To help better understand what’s important to your teen when she buys jeans, check out Seventeen .  The online magazine recently conducted a survey to find out why gals buy one type of jean over another. Some of the criteria used for rating jeans included:

Best Skinny Jean
Best Dressy Jean
Best Bargain
Best Jeans for Short, Tall, and Plus Size Girls
Coolest New Color

What’s your daughter’s favorite style of jeans … and do you approve?

Short, long, or somewhere in between…  Whatever your hair length, you can look like a celebrity. Check out these famous coifs for inspiration:

SHORT
Victoria “Posh Spice” Beckham defines short hair, getting edgier with each changing style. From the much-imitated inverted bob to her current pixie cut, Posh is a short-hair icon.

If you think your short hair limits your style options, consider playing with color. Pink can rock it straight and blonde or silver and curly.

MEDIUM
Gossip Girl’s Taylor Momsen always looks trendy with blond, carefree locks that just brush her shoulders.

Christina Aguilera is always changing her look, but her latest ‘do — with funky baby bangs — keep this talented mom looking young and fab.

LONG
Straight. Curly. Bangs. No bangs. Disney superstar Selena Gomez can do no wrong with her healthy chestnut locks.

American Idol Jordin Sparks makes the most of her long mane, glamming it up with a bouffant ponytail or wearing it down for that girl-next-door look.

Blake Lively’s golden ringlets. Katie Holmes new extensions. Paris’ sideswept waves. Halle’s cropped perfection. Who’s hair do you envy?
