I walked out of my Brooklyn apartment this morning for my daily iced matcha latte, and to my surprise, it was so brisk outside that I had to order a hot matcha latte. This means we've officially entered the sweater-weather portion of fall. So far this season, I've gotten by with wearing long-sleeve tops and layering light jackets over my T-shirts, but today, I had the chilly experience that I needed to start wearing chic lightweight sweaters.

As a fashion editor, I'm constantly scrolling through sites that offer affordable yet elegant options for each season, and fall is no exception. I've looked through an array of retailers to find the perfect lightweight sweaters and found that Zara, J.Crew, and Reformation offer the best ones at reasonable prices. These sweaters range from cashmere to cable-knit, so whatever your style is, there's something for you in the selection below. If you're on the hunt for a new lightweight sweater, keep scrolling.
