Kendall Jenner doubles up her free the nipple fun in two sheer shirts in 24 hours

The festival may end, but the fashion? That's hard to shake.

After spending the weekend at the Panorama Music Festival on New York City's Randall Island, Kendall Jenner hit the streets of Manhattan in two very sheer shirts in just 24 hours.

On Sunday, the 21-year-old model stepped out in Chelsea in a low-cut, bold red tie-up top with flowy sleeves, high-waisted straight leg jeans and her beloved white booties.

Despite how sheer the shirt was, Jenner opted to go sans camisole or bra. We're guessing it was a look happily approved by her BFF Bella Hadid, who was by her side in the same color scheme and has been a true champion of the Free the Nipple campaign this summer.

Then on Monday, the Keeping Up With the Kardashians star kept the translucent love alive in a long-sleeve black floral turtleneck tucked into cut-off boyfriend shorts. She accessorized with the same oval sunnies from the day before, sky-high, neon pink strappy stilettos and a Louis Vuitton fanny pack.

Jenner is nothing if not consistent, and she's been going hard on bringing back not only all things '90s but also the high fashion brand's early aught bag styles.

Jenner seems pretty dedicated to spending her entire summer in as few undergarments as possible. Just last week, she shared a completely nude black-and-white pic to Instagram, and earlier this month, she posted a selfie of her insanely toned tummy, major underboob and a lacy black thong simply captioned, "jet lag."

It's hard to tell if Jenner has been influencing Hadid or the other way around, but either way, the model pals have been spending a ton of time together lately. Watch the video below to relive their recent party hopping European adventures.
