Not all tights are created equal, no matter the price point. In punishing winter weather, E.G. Smith’s comfy, substantial pairs are our new staple. Made of 70 percent cotton and 25 percent nylon, they’re noticeably warmer than nylon-based styles, and the fabric gives them a richer hue than typical opaque tights and a softer, legginglike feel. The structured toes and heels prevent bunching, and though the elastic waist is standard — none of Commando’s or Spanx’s stomach-shaping qualities, unfortunately — it is thicker than bargain brands, so it stays put without sagging or digging into your waist.
