This cotton crewneck in a custom stripe is the perfect thing to layer under a sweater, or to wear plain if you're feeling delusional about the weather. Made with slub jersey, which means this shirt's yarns are thicker in some parts and thinner in others. This gives the fabric texture and depth, so it's not just a solid tee.
