It’s no secret that winter fashion is all about the art of layering; the goal is to find the perfect combination of pieces that keep you warm without looking overstuffed. And after seeing Martha Stewart’s recent Instagram post, I’m convinced there’s one closet staple that’s essential to achieving that. 

Stewart wore an oversized, double-breasted olive blazer, which she layered on top of a crisp, matching button down and skinny brown pants. The outfit was sophisticated while still being winter-appropriate and, thanks to the oversized nature of her coat, didn’t look crowded. 

A big blazer is Hollywood's winter layering secret; Naomi Watts, Margot Robbie, and Brooke Shields have all rocked the chic-but-practical top layer that even Gen Z loves. It can instantly elevate an outfit while still being relaxed enough to rock with a pair of jeans and roomy enough for your thickest winter sweaters. Plus, it looks just as good come spring with your go-to white T.  

To help you achieve Stewart’s look, I found eight oversized (but polished) blazers you can shop, starting at $36.

The Drop Blake Long Blazer

The Drop’s Blake Long Blazer is a favorite among Amazon shoppers, boasting more than 4,200 perfect ratings. Right now, select colors including a classic mocha brown are on sale for just $38. According to one person who deemed this “the perfect blazer,” the “relaxed fit” is “very comfortable and figure-flattering,” noting that the long, oversized silhouette allows it to be easily dressed up and down. Others were impressed by the quality, with one shopper saying that it “looks like a luxury item” while another described it as “rich, gorgeous… [and] silky.”

Wayf Oversize Double Breasted Blazer

Wayf’s 40-percent off blazer is a dead-ringer for Stewart’s. Like the star’s style, this pick also has a sophisticated double-breasted closure, sleek, notched lapels, and a deep olive-green hue. The material features a shiny, satin-like finish that elevates the trending style without feeling stuffy or overly dressed-up thanks to the relaxed fit.

Madewell the Rosedale Blazer in Crepe

I’m pretty loyal to Madewell’s blazers, which always bring a cool-girl edge to the more formal style; it’s no surprise the brand’s now-$70 Rosedale Blazer tops my wishlist. This double-breasted style is available in black and a washed-out blue and, according to shoppers, is a “wardrobe staple.” Customers love how versatile the style is, writing that no matter what they pair it with — jeans, trousers, mini skirts — the look always feels “modern and classic.” Others were obsessed with the “flowy” fit, which one person wrote “falls perfectly” and is “flattering.” One fan even raved, “I feel so hot and cool in it.”

Stewart’s oversized, polished blazer was proof that winter fashion doesn’t have to be frumpy. Shop more styles inspired by the layering hack Hollywood relies on, below.
