The Silver Lining collection, which features four popular On-the-Go pant silhouettes, sold out in just two weeks after landing on the site. Crafted with the brand's signature four-way cotton stretch material, the pants are lined with a special fabric that provides 100 percent opacity — technology that's been seven years in the making, according to Spanx. Celeb ambassador Ashley Graham confirmed to PEOPLE that white pants are non-transparent when she put them to the test. "I didn't believe it," she told PEOPLE in an exclusive interview. "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!'" While all four pant styles are back in stock, the On-the-Go Kick Flare Pants are already sold out in nearly all regular inseam length sizes, but are still available in sizes XS to 3X in petite and tall options. The pull-on pants have a completely smooth front free of a button and zipper, two functional back pockets, and a slightly flared hem.

It has the same features as the Kick Flare, but with a skinny ankle. Courtesy Shop now: $148; spanx.com The 4-inch and 6-inch On-the-Go Shorts are also both fully in stock. Like the longer-length pants, the shorts have a pull-on style and back pockets. The 6-inch inseam goes up to size 3X while the 4-inch is available up to XL.
