The hottest accessory of the summer is actually, well, pretty hot.

While we usually associate warm weather with breezy basics, this season celebrities like Jennifer Garner, Reese Witherspoon and Gwyneth Paltrow can’t help but top off their outfits with lightweight sweaters. From the streets of New York to the coast of Capri, stars are stepping out in cozy knits that they effortlessly throw over their shoulders – and we don’t see this trend slowing down anytime soon.

Thanks to their cozy feel and versatility, cardigans are a practical piece to have on hand. Whether you tie one around your shoulders on a warm late summer day like Garner, Witherspoon and Paltrow, or layer it over tank tops and T-shirts in cooler temperatures, lightweight sweaters are a wardrobe staple that you’ll be wearing for seasons to come.

We’ve rounded up celebrity-inspired cardigans and sweaters on Amazon, with prices starting at $12.

Celebrity-Inspired Cardigans

Witherspoon added a pop of color to her outfit by tying a bright cardigan around her neck, and this sweater from Amazon looks similar. The cardigan comes in 17 bright and neutral colors, including light pink and khaki. It’s “perfect for layering,” according to shoppers, and can easily be “dressed up or dressed down” depending on the occasion. Follow the actress’ example by throwing it over your shoulders, or wear it as a top with jeans and skirts.

“This is the first piece of clothing I’ve purchased from Grace Karin and I love it,” wrote one reviewer. “Thick enough to wear in too-chilly places like my office or a restaurant; not a cheap, flimsy material.”

Crewneck sweaters are also a practical staple to have on hand when you need a quick outfit change. Channel Garner keeps it casual and snags this white sweater for $35 off right now. More than 2,400 Amazon shoppers have given it full marks, highlighting its “buttery soft” feel and “cozy, oversized” fit in their reviews. Plus, several reviewers noted that it’s “perfect for fall.”

“(This sweater is) nice enough to wear to the office and secretly feels like wearing the most comfortable sweatshirt or pajama top ever,” wrote one shopper. “So soft and versatile.”

Paltrow isn’t the only celebrity reaching for black-and-white striped sweaters lately: Lindsay Lohan also put her fashion stamp on the classic on the set of Jamie Lee Curtis. Take a leaf out of their book and snap up this “luxurious” lookalike, as one Amazon shopper called it, while it’s on sale. Thousands of Amazon shoppers have added it to their carts over the past month, with several reviewers noting that it “looks more expensive than it is.”

“A very smart and professional sweater for work,” wrote one reviewer. “(It’s made of) a heavier blend fabric that’s great for colder climates or even layering during the transitional seasons.”
