Last year, amid her budding romance with Timothée Chalamet, Kylie Jenner was photographed wearing uncharacteristically romantic clothing—a far cry from her usual sleek, 𝓈ℯ𝓍y, and experimental ensembles. Paired with a healthy-looking blowout (in her natural shade of deep brunette), and minimalist, barely there makeup, Jenner’s new aesthetic made her almost unrecognizable.

As winter approached, she seemed to revert, at least a little bit, to the slick, daring fashions with which she’s become synonymous. Case in point: While promoting her latest venture, a line of vodka seltzers called Sprinter, the 26-year-old stepped out in a skintight Ferragamo micro-minidress with a wide belt resting on her hips. The look is peak Kylie Jenner. But that’s not what fans are focused on.

In photos shared on March 21, Jenner flashes a rarely seen accessory: her megawatt smile. In the comments, fans couldn’t stop gushing over it. “Okay smile at the end,” wrote one follower, while another added, “The last picture is the most genuine smile! Love it!”

Later that day, Jenner and her momager, Kris Jenner, and big sis Khloé Kardashian attended a launch party for Sprinter. The whole family kept it monochromatic, with Kylie in a plunging patent black dress and nude-illusion heels.

In front of the paparazzi, Jenner played it cool, making sure to flash the Sprinter label on her can while walking from her SUV to the party door. Though, once she made it through the doors, I’m sure she was smiling wide among family and friends. Vodka does that to me too, Khy!
