A long-sleeve crop top in smooth stretch jersey, with a classic crew neckline and thumb holes stitched into the cuffs to keep sleeves in place under a jacket. The thumb holes are a genuinely functional detail rather than decorative, holding the cuff down over the wrist so the sleeve doesn't ride up when you're reaching or moving. A gathered seam at one side of the waist pulls the fabric in for shape, and the hem crops just above the navel, pairing naturally with high-waist jeans or leggings. It works equally well as a standalone top for running errands or as a base layer that stays put under a bigger jacket or coat.
