V-Neck: Everlane's Seed Stitch V-Neck

A solid, neutral v-neck is a wardrobe staple. For summer, try this lightweight piece from Everlane that is a blend of cotton and cashmere (and yes, it's as soft as it sounds). It's available in dark grey, light grey, and navy, which means it goes with almost any ensemble, and falls in line with the super-low prices the brand has become known for. [$55, everlane.com]
