Khloé Kardashian's Good American brand launches activewear

Khloé Kardashian may have her own fitness closet packed with sneakers, sports bras and leggings, but to hear her Good American co-founder Emma Grede tell it, nothing ever felt perfect — so the star decided to make her own workout pieces.

“Khloé wanted to do activewear from the beginning,” Grede told Page Six. “I have to give her that credit! Activewear is what she lives in, so she really came into this knowing exactly what she wanted.”

The challenge, Grede added, was creating a line that stood out in a crowded market — and, in keeping with Good American’s size-inclusive ethos, would fit and flatter sizes XS through 4XL.

“At Good American, we’re all about problem-solving,” she said. “There are lots of leggings out there, so how can we offer something superior?”

The answer is a collection, which launched Thursday, of high-waisted leggings, sports bras, tank tops and hoodies priced from $59 to $149 and done almost entirely in black and white for maximum mix-and-matchability.

This being a Kardashian-adjacent enterprise, there are even bike shorts.

Fitness is an integral part of the youngest Kardashian sister’s personal brand: In addition to undergoing her own slimmed-down makeover on “Keeping Up With the Kardashians,” the star is the host of E’s “Revenge Body.” And following the birth of her daughter True Thompson, Kardashian has been proudly flaunting her post-baby physique on social media.

“We did a workout together the other day — [she was] three months postpartum, and I’m trying to keep up with her,” Grede said. “She trains six day a week and is incredibly fit. Khloé’s hardcore — a beast, as they say.”
