We finally hit the time of the year when the weather can't quite make up its mind. Lightweight knit tops are the way to go when you don't know what to expect. Breathable enough for sunny late-summer days and cozy for cool fall nights, we found 17 knit tops on Amazon that bridge the gap between comfort and style - all under $25. Versatile and chic, these transitional tops feature plush material that layers under blazers without feeling too bulky. From waffle knit tops to puff-sleeve tees, these picks add a refreshing touch to any wardrobe.
