J.Crew Women’s Short-sleeve silk-blend crewneck sweater

Think of this as the perfect warm-weather sweater—or like an extra-special T-shirt. Either way, it's one of your new favorite styles for both work (under a blazer) and weekend (with jeans). It's made from a lightweight, drapey fabric with a compact knit—so it's super-breathable, but never see-through. TENCEL lyocell/acrylic/polyamide/silk.
