21 Winter-Ready Blazers That Are Warm Enough to Keep You Cosy

When it comes to identifying the most-popular blazers, a few styles come to mind instantaneously. Checked blazers are always a strong choice; leather, too. As are classic black and cream shades, which will go with just about anything you choose to wear underneath them. But when it comes to the colder months, there’s one blazer style I prioritise above the rest: those of the woollen variety.
As someone who wears blazers almost every day (at least, the days I venture outside of the house), I’m so glad wool blazers exist. As we all know, wool is one of the toastiest fibres out there, and selecting a wool blazer means I can continue to wear it even on the chilliest of days without feeling a chill.
Don’t get me wrong; I still have a camel robe coat I can wear when I need more coverage and insulation. However, more often than not, a wool blazer is the outerwear I reach for most days because it has the power to make even the most casual of outfits feel more polished. I tend to wear mine with jeans and a cable-knit jumper, but it looks just as sleek with midi skirts.
Wool blazers tend to cost more than their non-woollen counterparts, as the fabric is more expensive to produce than, say, cotton. But the typically hip-length and minimalistic shape of blazers means they work with most outfit silhouettes—everything from miniskirts to wide-leg trousers. I’ve certainly got the use of my & Other Stories wool blazer, and I see no reason you wouldn’t get the same cost per wear out of whichever you choose.
There are so many great wool blazers for women out there, but I’ve whittled them down to the 21 best. So keep scrolling your perfect winter cover-up.
