Getting dressed during that in-between stretch from winter to spring can feel like a daily guessing game. One minute it's chilly, and the next it's surprisingly warm, which makes heavy knits and flimsy tees equally frustrating. That's where short-sleeve sweaters quietly save the day, offering just the right amount of warmth, while still feeling light enough for brighter, milder afternoons. These versatile knits are a transitional wardrobe staple for a reason. They layer beautifully under jackets when mornings are cool, then stand perfectly well on their own once the sun comes out.
