9 Fall-Friendly Thin Sweaters Under $100

Now’s the perfect time to wear a thin sweater under a blazer.

Getting dressed for work shouldn’t be a bore. Welcome to Business Casual— here to make your weekdays easier.

The moment the temperature dips below 70 in the fall, everyone’s eager to declare it sweater weather. But not all knits are created equal — you don’t need to bust out that chunky turtleneck when it’s barely chilly. For these temperate days, a thin sweater is your best friend. Treat them like a dressier, work-friendly version of your favorite white T-shirt and tuck it into a midi skirt or slip it under a blazer. Then when it legitimately gets cold, you can use it as a base layer under warmer clothes. With plenty of options under $100, you can buy a few and rotate them throughout the week, making getting dressed in the morning that much quicker. Scroll ahead to shop our favorites.
