We still have about a month before it's officially fall, but the weather has already been shifting towards cooler autumnal temperatures. With warm days ending in breezy evenings, you could say it's not as easy to dress for the in-between weather. That's why it's important to have transitional knit tops in your rotation, like these 19 picks. Take it from Us, it's never too early to add summer-to-fall clothes to your wardrobe. But if you don't know where to start, don't worry! We rounded up cute options, including knitted vests, lightweights shirts and airy cardigans.
