“Twice is nice,” is probably what Khloe Kardashian is thinking after her denim brand, Good American, sold out of its popular ‘Good Waist’ silhouette Thursday for the second time since its October debut.

Fans scooped up the jeans almost as quickly as Khloe’s half sister, Kylie Jenner’s lipkits.

The jean collection offers a range of sizes to fit curvy girls, from a size 0-24, and three silhouettes: boyfriend, skinny and high-waisted. The collection retails for $149-$215 and are available online and at Nordstrom.com.

Kardashian Instagrammed her behind in Good American jeans, and captioned the post with a thank you message to shoppers and fans.

“You guys are the best!! @goodamerican Good Waist has sold out TWICE since we launched in October,” she posted. “I am so beyond proud and excited that you are loving this denim revolution and loving your curves!! It will be back in stock soon so join the waitlist at goodamerican.com.”
