Ever wondered how even when a celebrity is out shopping or grabbing dinner with a friend, they always seem to look both polished and effortless? Well, there’s most likely a stylist behind their low-key ensemble. That, and a stylist’s trusty capsule wardrobe, or as they call them, their “kit,” which many in the business, including Hollywood styling veteran and Affirm partner Tara Swennen, swear by. In fact, the celebrity stylist of more than 20 years never heads out on a job without it. 

To find out how we, too, can get that same nonchalant look that every well-dressed celebrity has, I called on Swennen to find out what exactly lives inside her kit. And just like when she dresses clients like Kristen Stewart and Allison Janney on the red carpet, she didn’t disappoint. 

Clothing-wise, Swennen tells Who What Wear, that her styling kit is all about the classics. “Those tend to be neutral pieces, such as white and black tanks and tees; black, [skin-tone], and red pumps and strappy heels, black and white trousers; and neutral blazers.” For her, the key is to find and invest in upscale basics that will “stand the test of time,” she says. “Trends are constantly evolving, but ageless, staple pieces that are high quality and built to last will survive not only the four seasons but [the entire year].” 

Knowing that splurging on pricier essentials isn’t always the easiest or most possible route for shoppers, though, Swennen is joining forces with Affirm. “I’ve found Affirm to be really helpful in making these investment purchases because it lets you buy the essentials you need now, but spread out the costs over time,” she says. That way, you can build your own life-long capsule wardrobe without obliterating your monthly budget. 

With that in mind, see what wardrobe essentials this stylist of 20 years swears by and finally unlock the secret to all your favorite celebrities’ effortless aesthetics.
