Talk about an ingenious  — or should we say, in-jeanius? — fashion hack.

While Rag & Bone’s Miramar jeans are a dead ringer for denim, they’re just as soft as sweatpants — and right now, select colors are on sale for 30% off at Nordstrom.

In addition to the classic blue Miramar Fleece Terry Sweatpant Jeans, which are currently flying off the shelves, new markdowns also include the brand’s trendy two-tone Miramar Sofie Sweatpant Jeans.

In addition to skyrocketing to internet fame, the comfy style staple’s racked up plenty of celebrity fans — including Kyle Richards and Madison LeCroy, who both own different shades of the Miramar Sofie Jeans.

Meanwhile, Brittany Mahomes paired the tapered Miramar Terry Jogger Pant with a matching jean jacket at a Kansas City Chiefs game in November.

They sought-after style’s a hit with editors and fashion pros, too — like The Post’s VP of Influencer Marketing & Franchise Growth Kristin McNamara, who gave it a rave review in November.

“If you haven’t tried Rag & Bone’s magical Miramar denim yet, you are missing out,” she wrote at the time. “They’re sweatpants that look like jeans — so they’re kind of the perfect pants to pair with overeating during the holidays.”

The buzzy collection also includes hoodies, track pants and several styles of shorts, all created with the brand’s unique denim printing process.
