From pants with hole-punched hips to cold-shoulder tops with a twist, there's no denying that skin was, well, in. But leave it to none other than Rihanna to take the already sexy trend to an even more risqué level. On Saturday, the singer modeled several looks from Savage x Fenty lingerie line on Instagram. In the first few photos, RiRi posed in blue plaid short shorts with a lace waistband, a matching bra, and an oversized button-up shirt. She paired the look with box braids and minimal makeup — including a glossy lip and dewy skin. @badgalriri/Instagram It wasn't until the final slide in her Stories that Rihanna debuted pajama bottoms with a chaotic butt cleavage cutout. From the front, the tartan-patterned pants look like your average pajamas, but from the back, they were anything but (no pun intended). The cheeky cutout was accompanied by an adjustable tie from behind. @badgalriri/Instagram Rihanna and Her Leather Miniskirt Taught Us the Ultimate Lesson in Monochromatic Dressing The open-back PJs are just one of many new pieces in Rihanna's holiday collection.

"holiday szn bout to be Xtra af," she wrote alongside the snapshots. In a separate post, she uploaded a video from the same photoshoot, captioning the clip: "All he want for Christmas." Tis the season, indeed.
