Someone’s a good little sister! Miley Cyrus recently gave big bro Trace a hand, helping him create a T-shirt for his two-year-old Southern Made Hollywood Paid clothing line.

“We decided to create a shirt that represented my line, with some of Miley’s style added to it,” Trace said in a release. “The two of us had been talking about doing this for a while — it was just about getting the right design.”

Trace came up with the idea for the artwork, basing it on his sis. “I wanted to think of something that really reminded me of [her],” he said. So he chose to feature a dream catcher, reminiscent of Miley’s biggest tattoo, and an image he has tattooed on his body, as well. “It was something we were always around since childhood, because of the influence from our dad,” he shared.

The addition of a peace sign and Miley’s autograph complete the shirt. “It just felt appropriate to somehow incorporate,” Trace said of his sister’s signature.

The shirts ($28 each) are available now on the Southern Made Hollywood Paid website, and proceeds from all sales benefit Miley’s Pappy Cyrus Family Foundation, which helps needy children with health care, medical treatment, education and more.

Sporting fashionable ensembles no matter what the task seems to come naturally for Beyoncé. So when she decided to teach kids a few dance moves during a surprise visit to a middle school on Tuesday, she made sure they were styling for the occasion, too! The superstar got a group of students moving on the dance (er, gym) floor when she stopped by for an unannounced visit at New York’s P.S. 161 in Harlem, toting custom-designed T-shirts by her label, Deréon. The visit was made on behalf of First Lady Michelle Obama‘s “Let’s Move” initiative, a campaign aimed at encouraging young children to make healthier lifestyle choices. The black tees, emblazoned with the “Let’s Move” logo, came from a collaboration between Beyoncé, her mom Tina Knowles and the first lady. Though they aren’t available for sale, they will become the official shirts of the growing campaign. It looks like Beyoncé really does have an outfit for every occasion! –Kim Peiffer

For the past two summers, he and his Jersey Shore co-stars have spent their summers working at a T-shirt shop in Seaside Heights, N.J., and now Ronnie Ortiz-Magro is ready to share his expertise with the world, by launching his own line, called Jersey Laundry. “The crowds in Jersey wait in line for hours for shirts that say ‘Team Ronnie,’ or ‘I Heart Vinnie,’” he explains. “We’re going for stuff like that, and running with it.” The line, which he’ll be previewing Friday in Dallas and Saturday in Las Vegas, will feature some of Ortiz-Magro’s sayings and a few images of him as well. Some examples? “‘GTS, gym tan smush’,” he says. “They’re more for the younger fan base. Funny stuff like, ‘Got Smush’? ‘Have You Smushed Today?’” The shirts, which will roll out on their own new website in late February and cost about $20 apiece, will start with three men’s shirts and three women’s, including one that reads, “I [Heart] Single Ronnie.” Still, he won’t confirm whether he’s on the market: “You gotta wait and see for the season how things pan out and see where that goes,” he teases. “Every episode is more and more drama—it’s not gonna get dull!” One thing he’s happy to gush about? Filming season four of his hit show in Italy this spring. “As soon as I heard, I put an order in for a Rosetta Stone,” he says. “I need to know how to order grilled chicken when I get down there—I can’t have pasta everyday!” And expect to see him rocking Jersey Laundry overseas. “We’ve got T-shirt time, and now I’m making the T-shirt!” he laughs. Tell us: Will you buy a T-shirt from Ronnie’s new line? — Lesley Messer

When Alexa Chung’s collection for Madewell launched this fall, the pretty dresses and chic basics went flying off shelves, but for anyone who missed out the first time around, the retailer is now giving you a chance to score a previously unreleased item from the original line! Tomorrow, Madewell will add Alexa’s bat tunic to the shoppable mix and no one is more excited than the British cool girl herself. “I’m so happy that the tunic is now available,” she tells PEOPLE. “I loved the bat tee but was always rather fond of the longer version.” If the weather prevents you from donning it solo with lace-up hiking boots, the fashionably quirky Brit is not short on seasonal styling tips for the cotton T-shirt dress. “Wear with tights and a grandad cardigan this winter or wear it to bed so you can look ace even as you sleep,” she advises. Priced at $58, the bat-emblazoned tunic will be available online at Madewell.com starting Dec. 2. Tell us: What do you think of Alexa Chung’s Madewell collection and will you buy the bat tunic? – Hana Choi

Gwyneth Paltrow‘s weekly newsletter Goop.com has always been a chic source of well-informed ideas for the savvy shopper, so it only makes sense that the actress-turned-singer would get into the holiday spirit by curating her own gift guide. “Anything personally made for you always trumps other gifts because of the thought and organization put into it,” Gwyneth writes. Her selection includes eclectic finds like customized holiday cards from Cocodot.com and trinkets from Vicente Agor, a San Francisco-based jeweler, who (for $310 and up), will turn a profile picture of your loved ones into one-of-a-kind pair of earrings.

Most models come and go in the blink of an eye, but Naomi Campbell has remained a constant on the catwalk and magazine covers for the last 25 years. And what better way to celebrate a quarter century as a supermodel than with your very own T-shirt collection designed by Domenico Dolce and Stefano Gabbana, as well as a slew of fabulous parties? “Besides being one of our favorite models, Naomi is also a great friend and a special woman,” said the designing duo. “What matters for us, and what we would like to celebrate, are the private moments that we shared and that allowed us to know her generosity, her funny jokes and her being always ready to help those who needed it.” And celebrate they did: Naomi was not only fêted at Fashion’s Night Out and London Fashion Week parties, but also toasted at another star-studded bash that the designers threw at the Dolce & Gabbana boutique in Milan on Sunday. The limited-edition collection of 14 different T-shirts–each with an iconic image of Naomi taken by legendary fashion photographers like Mario Testino and Patrick Demarchelier–will be sold for $200 exclusively at Dolce & Gabbana boutiques with a portion of proceeds going to Naomi’s charity, Fashion for Relief, which raises funds in the fashion world in time and places of need. –Jessie Goldberg

Betty White is now adding a new title to her name: Fashion drill sergeant. With the launch of “The Betty White” limited-edition collection for Jerry Leigh Apparel, a line of hoodies and T-shirts—priced from $48—comes a promotional behind-the-scenes video featuring our favorite Golden Girl hard at work in the business of fashion, and being anything but polite. Watch as a tracksuit-clad Betty rolls up in a sports car and gives her manufacturing team a lesson in hardball management. “If I ask you to sew, you say how fast? And if I ask you to iron, you say how hard,” she quips. But at the end of the day, Betty just wants to spread the love. “When you buy a Betty White product, you get so much more than just fabric and thread, you really get a little part of my heart,” she says. Watch this not-to-miss video or visit hoodiebuddie.com to make Betty White a staple brand name in your closet — and help support the Morris Animal Foundation, which receives a portion of the proceeds from the line’s sales. –Jessie Goldberg
