The celebrity-loved brand recently relaunched some of its On-the-Go pant styles in white with a special feature: Spanx's Silver Lining technology, which provides 100 percent opacity. According to Spanx, the tech has been seven years in the making; in addition to being non-transparent, all four silhouettes are made with a four-way cotton stretch fabric and have a pull-on design. To celebrate the new collection, Spanx enlisted its first-ever celebrity ambassador, Ashley Graham, who put the white pants to the test. In a PEOPLE exclusive interview, Graham shared that she "screamed" when she saw how opaque they were. "I didn't believe it," she told PEOPLE. "Then I had a fitting and I wore black granny panties on purpose, and sure enough, I put on the pants, I bent over in front of the mirror, and I screamed to my assistant, 'You can't see the underwear!'" Courtesy Shop now: $148; spanx.com One of Spanx's most popular On-the-Go pant styles, the Kick Flare Pant, is available with the Silver Lining tech; this style is currently completely sold out in the black, navy, and red colors it originally launched in. The pants are available in sizes XS to 3X and three inseam lengths: regular, petite, and tall. Thanks to the pull-on style, they have a completely smooth front, free of a button and zipper, and have two functional back pockets.
