Sporting timeless, classic pieces is an everyday occurrence for Martha Stewart. The entrepreneur recently attended a dinner honoring J.Crew and posted a selfie in the comfiest ensemble. Of course, she was dressed to impress, rocking a cozy sweater that we want in our own winter wardrobes. It turns out that Stewart was wearing J.Crew's Rollneck Sweater, a throwback style that the brand re-released earlier this year. While no doubt dreamy, it'll set you back almost $100.
