4 celebrity fitness lines: Yoga pants are the new perfume by Christina Valhouli @FortuneMagazine March 7, 2015, 8:47 AM EDT E-mail Tweet Facebook Google Plus Linkedin Share icons In the past decade, we’ve seen A-list celebrities lend their names to everything from perfumes and Proactiv acne treatment to Nescafé coffee makers and luxury haircare. But the latest bandwagon is a more surprising one: fitness apparel. In the past year or so, celebrities ranging from the actress Kate Hudson to the singer Carrie Underwood, along with television host Brooke Burke-Charvet have all launched activewear lines. According to WWD, Beyoncé will debut a fitness line with Topshop in late 2015. New Balance has collaborated with supermodel Heidi Klum, and Adidas has worked with Pharrell Williams, Selena Gomez and Rita Ora — but an Adidas company spokesperson emphasized that these collections fall under “lifestyle” rather than fitness. Demi Lovato is the face of Skechers sneakers, and singer Rihanna is Puma’s creative director. So why have derriere-enhancing yoga pants replaced pricey perfumes as the celebrity product of choice? Euromonitor International research analyst David McGoldrick says that fitness brands are having a moment, and have never been more popular. “The top fitness brands such as Nike NKE and Under Armour UA have had a great couple of years,” he says. “Fitness wear is the hot thing right now.” According to Euromonitor International, sportswear increased by 4% in current value terms in 2013, to reach $81.7 billion. McGoldrick also chalks it up to the cross-over appeal of “athleisure” clothes. “If people were only wearing it to the gym, the sales wouldn’t be so big.” Translation: moms who attend yoga class, hit Starbucks and then spend the rest of their day in their compression pants and hoodie are helping to boost sales. A-list stars launching their own lines, or partnering with an established brands makes perfect sense, McGoldrick says. “Celebrities bring their name to a brand as well as a built-in market and fan base,” he says. “Name recognition plays a big part.” Of course, it also doesn’t hurt when the celebrity sports a six-pack and flawlessly toned legs. Kate Hudson, a co-founder of Fabletics, wanted to make a product that allowed women look just as stylish in the gym as well as running errands. “We wanted to create something that would be much more than something to work out in, but something to live your busy life in, something that is functional, comfortable, stylish and affordable,” she says. “Affordable” seems to be the ethos for many of the celebrity owned (or designed) brands, which are often priced at a mid-range level, in order to appeal to a broader market. One of the newest lines to hit the shelves is CALIA by Carrie Underwood, which debuted at Dick’s Sporting Goods DKS in early March. “We felt there was a gap in the market for fitness clothing that would work with your entire lifestyle,” says Lauren Hobart, the chief marketing officer at Dick’s Sporting Goods. “You can live your whole life in CALIA. It’s fashionable and also includes items like sweaters.” Hobart says that Underwood has been the line’s lead design partner and has been involved in all aspects of it, from design to functionality. “She is the busy female fitness consumer,” says Hobart. And with a new baby, we expect she will be even busier. Here’s a closer look at four celebrity fitness lines.
