Reese Witherspoon’s Fair Isle Sweater Is a Top Winter 2025 Trend

Reese Witherspoon is a class act—and she has the closet to prove it. The multihyphenate’s outfit rotation is comprised of timeless, sophisticated styles that nod to her unofficial role as Hollywood’s sweetheart. In true Witherspoon fashion, the star just sported winter’s most classic piece: a fair isle sweater. Naturally, I already tracked down five similar styles, and prices start at just $24.  

Believe it or not, the following knits are all less than $45 at Amazon. Below, browse through chunky crewnecks and cardigans from shopper-loved brands including Amazon Essentials and Derek Lam. Just be warned: You’ll wear these sweaters on repeat through next season. 

Best Under-$45 Winter Sweaters

Amazon Essentials Crewneck Sweater

I instantly fell in love with Witherspoon’s traditional fair isle crewneck, and my jaw dropped when I spotted a nearly identical pick for under $25 (thanks to its coupon). This Amazon Essentials option boasts the same look at the star’s—even down to its zig-zag pattern and blue colorway. Another cart-worthy pick from the brand: This super soft sweater features versatile neutral tones that’ll pair perfectly with the rest of your winter wardrobe.      

Dokotoo Chunky Fair Isle Cardigan

If cardigans are more your speed, you’ll adore this Dokotoo pick, which happens to be less than $40. (Score!) The sweater is ideal for layering thanks to its boxy, comfortable fit. My personal favorite touch? It has elevated tortoise buttons, and, of course, a statement print. 

Derek Lam Crosby Diagonal Fair Isle Sweater

For a unique spin on the traditional fair isle pattern, opt for this diagonally-printed Derek Lam number. In addition to its ultra-chic detail, the pre-loved designer piece features a snuggly turtleneck to keep you comfortable all season. Speaking of warm-and-fuzzy finds, be sure to check out this mock-neck Nautica style before heading to checkout. Beyond its cozy collar, it has subtle balloon sleeves for an added element of style. 

Head to Amazon to snag these Witherspoon-inspired knits while they’re available from $24 this winter.
