Are our calendars wrong, or are the ’90s really back? We’re asking because it seems like flashing your Calvin Klein underwear over the top of your jeans a la Marky Mark is a hot fashion trend once again, and the who’s who among celebrities are jumping on it left and right.

We could say that Kendall Jenner is the no. 1 promoter of this pants-down trend. She temporarily shut down the entire Instagram website when she posted a half-naked photo of herself in a matching Calvin Klein sports bra and underwear showing over the waistband of very low-slung jeans.

“Morning! just going to hang out in #MyCalvins alllll day! … thank you @calvinklein for my little gifts,” Kendall captioned her photo. It then proceeded to receive nearly a million likes.

After Kendall’s Instagram snap went viral, we couldn’t help but see Calvin Klein underwear waistbands everywhere. We spotted it next on another young Hollywood hottie, Vanessa Hudgens.

The paparazzi first caught Vanessa giving a peek of her CK underwear over oddly bunchy denim shorts, but she later flaunted them herself on Instagram.
