The Underwear Every Kardashian-Jenner Wears on the Red Carpet

By now, you're probably well aware of the wardrobe miracle that is Spanx—the founder is even a bonafide billionaire. But are you really buying the most effective pieces from the brand? Monica Rose, stylist to the entire Kardashian-Jenner clan, told InStyle about the one specific Spanx undergarment she uses for her famous clients—and highlighted the mistake you might be making.

"I use a lot of Spanx—that's definitely my go-to brand," Rose told InStyle. "I use the high-waist ones that go all the way down to the calf. If you do the one that's short, it always leaves a line, so I always use the longer ones." Considering Rose's job entails dressing celebrities in the most flattering, camera-friendly looks possible, it's safe to say she knows what she's talking about. So you'd be wise to swap your short Spanx styles for longer ones whenever your outfit permits.

Associate Director, Fashion News

Erin got her start as aBest Knockoff Luxury Clothing intern over 13 years ago—back when the site only published a single story per day. (Who What Wear has since increased that number twentyfold.) She graduated magna cum laude from USC, which is how she ended up moving to Los Angeles from her hometown of San Diego. In college, she also interned at Refinery29, where she was promoted to editorial assistant and then assistant editor. After nearly three years at R29, she came back to WWW in 2016, where she currently holds the title of Associate Director of Fashion News (as well as the unofficial title of resident royal expert—in case you haven't noticed her numerous Meghan Markle and Kate Middleton stories). She spends her days trying to incorporate her idols, Anna Wintour and Roger Federer, into as many stories as possible. Outside of work, she loves tennis, classic rock, traveling, and smothering her dog with affection.
