When done right, blazers can be a star player in your wardrobe. They can take you from work to the weekend, add a bit of polish to an otherwise casual look, and even be worn as outerwear when temperatures begin to warm.
As a fashion writer and plus-size fashion expert, I get to test out a lot of options and hear feedback directly from my industry peers, so I’ve amassed quite a bit of knowledge about what is on the market and what is worth investing in.
After an in-depth review of what is available now, including wear-testing pieces and interviewing fashionable women in the know, I’ve rounded up the best blazers for every size range from petite to plus. I’ve also found blazers for different aesthetics and wardrobe needs, from sharp, office-ready wool suiting to casual, breathable fabrics that pair well with easy denim looks.
Read on for my picks of the best places to shop blazers in 2025. And if you’re building a full work wardrobe, see our pieces on the best women’s workwear, the best work bags for women, the best plus-size workwear, and more.

We love Spanx’s workwear because of the stretchy yet structured Ponte material the brand uses to construct its blazers and pants. In fact, this blazer is the companion to the pants we named the best black work pants — and they feature the same loungewear-like comfort.
“I love this piece because it’s a basic black blazer that doesn’t wrinkle, so it’s easy to take on trips. Plus, it’s super versatile because it isn’t made of seasonal fabrics like wool or linen. Spanx does it again with another piece made from their signature stretchy, super comfortable material.”
The Ponte Blazer paired with the Ponte Wide-leg Pant also made our list of the best suits for women.

Whether you live in a warm climate or just want to have cute blazers in rotation for summer months, finding a great lightweight blazer feels like a wardrobe victory. When I am shopping for warmer temperatures, I always look for breathable natural fabrics like linen and cotton (because who wants to be sweating in a poly blend in August?).
Natural fibers address that issue but also add the challenge of keeping the look sharp. Depending on the style, linen, in particular, can look very relaxed, which is not going to be the desired look for everyone. But if you want breathable fibers without the crunchy aesthetic, this linen-cotton blend blazer from Marcella NYC is an excellent option.
The structure built into the bodice keeps things looking sharp without being overly stuffy, giving it the versatility it takes for a true work-to-weekend-ready piece. I wore it more casually, with a bodysuit, Mary Jane ballet flats, and mesh maxi skirt from plus vintage favorite Berriez, and loved the effect. For the office, it would look great over a crisp button-down or a sleek sheath dress. Per their size chart, an XXXL is the equivalent of an 18/20, which is my usual size, and I found this to fit true to size. n

If you are looking for the type of gorgeous classic wool blazer you’ll have for a lifetime, Argent should be on your radar. This woman-owned NYC label makes the platonic ideal of this wardrobe staple, with a “Seasonless” 98% wool blend purported to be “naturally temperature regulating and odor and wrinkle resistant” – and it lives up to the claims.
I wore it on a day when the temperatures fluctuated wildly (from overly heated cafes to a balmy spring afternoon to a suddenly freezing evening), and I was comfortable—and gloriously unrumpled—throughout. The blazer even kept its shape after being tossed haphazardly in a restaurant booth during dinner—a true testament to its wrinkle resistance!
This fabric is excellent, and if you love it as much as I do, you are in luck: This particular blazer is available in 13 different colors, and there are other styles offered in the same signature wool blend, including a relaxed peak lapel blazer and a cool wrap vest (which looks fantastic on a curvy figure). I’ve found their sizing to be relatively true to size – my only suggestion is to size up in their double-breasted styles if you have a fuller bust and want the option to wear them buttoned up.

One of the best things about a good blazer is the instant structure it can add to an outfit’s silhouette, but sometimes that structure comes at the cost of real comfort, as many blazers are made with stiffer fabrics to retain the shape better. But with this style from NYC label T.W.I.N., you do not have to choose between structure and comfort.
The sustainably sourced punto di Roma fabric (the original Ponte!) holds the blazer’s hourglass shape while still feeling soft and yielding. It also wears wonderfully, resisting wrinkles and looking sharp even after a day of running around NYC to meetings.
One thing to note: T.W.I.N.’s sizing runs very generous in most stretch items, and that includes this 04 Double Breasted Blazer. I am a size 20 and haven’t been an XL in years, but I am comfortably wearing an XL here. So unless you are looking for an oversized fit, I absolutely suggest sizing up in this style (and that goes for T.W.I.N.’s staple 02 Knit Blazer as well.

There’s something cool and polished about a slightly roomy pinstripe blazer, and the cotton Michelle blazer from Nashville-based Able is a perfect example. It has enough structure to keep things office-sharp but not so much that it feels stiff or overly formal for day-to-day wear.
I’ve found Able’s sizing to run true to size and sometimes a little generous, so this is one brand I don’t recommend sizing up in. I got this pinstripe blazer in my usual 2x, and it fit exactly as I hoped it would. It is loose throughout, including the upper arms and across the bust (even when buttoned!), but doesn’t look slouchy or too big.
This blazer is fully lined, and the weight of the 98% cotton body is substantial, so it is a great option from fall to late spring – pretty much anything but high summer! I styled it with a cool striped dress for a little stripe print mixing moment, and I already have a bunch of other outfits in my mind that would look great with this. I feel like this is the type of piece you’d end up reaching for regularly.

Petite Studio makes clothing with petite needs in mind, and its Jane blazer is one of senior editor Sally Kaplan’s favorites. The front panel is cropped a few inches shorter than the back which is a thoughtful petite touch, and while the sleeves are slightly long on Sally’s 5’1 frame, it’s certainly not a dealbreaker. Paying $200 isn’t ideal, but the customization is worth it if you’re looking for a boxy blazer that’s made with a petite body in mind.
We recommend ordering your standard size. Sally typically wears an 8 or 10, and that’s the range given for the large — which is the size she’s wearing in the picture above.
Amazon
If you are the type of shopper that loves to find a style that fits and buy it in multiple colors, this blazer from Amazon’s The Drop should be on your radar. The one button, single breasted silhouette is versatile and classic, and the affordable price point makes getting a few colors less daunting of a splurge. More importantly though, it stands up to regular wear. Jewel Elizabeth, Author of The Encyclopedia of New York Fashion, has a collection of her own and recommends it heartily: “This Blake Blazer from Amazon’s The Drop is so good I have it in 3 colors. It fits a woman’s body, can be thrown in the wash, and comes in a ton of solids and prints.”
That’s no overstatement about the options, either: There are currently 23 (!!!) different colorways available to order on Amazon, ranging from basic black to vibrant red to silver sequin to blue velvet to soft sage. It is well reviewed too, with a 4+ star rating and over 8000 reviews. The biggest qualm people seem to have with it is that it can wrinkle easily, so keep that in mind if wrinkle resistance is a high priority for you
Universal Standard
One of the most important aspects of finding the perfect oversized blazer is the ability to size up. This might seem obvious and easy if you are on the lower end of the women’s size range, with lots of sizes above you and viral brands like Frankie Shop offering pre-oversized blazers, but if you are closer to the top end of a brand’s size range, you might not be able to get the same effect. So my favorite brand for oversized options is a brand with one of the most inclusive size ranges on the market: Universal Standard.
The Pinstripe Blazer is also part of Universal Standard’s unique Fit Liberty program, which allows no-fee size swaps within a year of purchase on select styles (look for the blue Fit Liberty badge on the product page to see if an item qualifies). That program also takes the stress out of figuring out your size, as you can always swap it out if you realize another size would fit you better.
Sezane
French labels have become the worst-kept secret over the last few years, with their charming Parisian interpretation of classic styles taking over fashion feeds. Without knowing otherwise, you might think this is a heritage label that has suddenly spiked in popularity, but Sezane was actually founded in 2013 as an online-first brand with thoroughly modern sensibilities, including a B-corp certification and extensive commitments to sustainability and supply chain transparency.
Sezane’s blazers are popular as a whole, but one style in particular was recommended the most: The double breasted Christie blazer. The style is lauded for being full-bust friendly and the type of item you reach for regularly. It also comes in a variety of colors and materials, including a blue cotton version that reads like a grown up take on the denim jacket, and a pretty sage wool blend. The sizing is generally true, if a little generous.
Finesse
If you are looking for of-the-moment trends and affordable designer-inspired pieces but don’t want to go the full-on fast fashion route, Finesse is an option you should know. With demand-based production, Finesse is trying to minimize the waste inherent in the fast fashion business model without sacrificing trendiness, and I think they are threading that needle deftly. Whenever I cannot find a specific trend in plus sizes, I check Finesse and almost always can find it there.
Finesse’s blazer selection is on the smaller end, variety-wise, but you can shop knowing that what they do have is current and cool, and at a very accessible price point.
The Zila Hourglass Blazer, for example, is a perfect take on the exaggerated proportions that are having a moment on the runways lately. I find that their styles run true to size too — just make sure to take a look at their size chart before ordering to confirm!
My one big tip for shopping Finesse is that you give yourself a big enough time cushion if you need a style for a specific event: Some of the shipping comes from overseas and can take up to 11 days if there are customs delays.
Ameliora
Finding a good blazer is not the only thing that is challenging – you also have to figure out how to best maintain it. Regular dry cleaning is the obvious answer, but anyone who is working long hours can attest that keeping up with that is easier said than done. So finding a sharp, machine washable blazer is a win for saving both time and money.
That might be why the Zoe blazer by woman-owned NYC label Ameliora is such a big hit with customers, and it is their best-selling blazer style. Founder Adrienne Kronovet highlighted Ameliora’s “signature Wash & Wear Italian suiting fabric,” saying that it “sets a new standard for quality and comfort. It’s machine washable, 4-way stretch, breathable, wrinkle resistant, and non-pilling.” (The latter is particularly notable, as washable stretch suiting can be notoriously pilly.)
Customer reviews also rave about the fabrication, emphasizing its comfort and packability, saying it is perfect for packing light, and that they love that they can wear it everywhere and then just throw it in the washing machine. The streamlined silhouette, high buttons, and minimal mandarin collar make the style versatile, too — it can be worn as a shirt, a blazer, or a jacket.
Lane Bryant
This heritage plus size brand has been around for over a century, and I always like to say that they took that time to perfect their plus fit — something that is particularly apparent in their blazers.
I was recently at a conference where plus-size influencer Georgette Niles led a session on optimizing your closet, and an audience member asked where to find the best plus-size blazers. Niles immediately replied, “Lane Bryant,” and all the other plus size fashion influencers in the audience (myself included) chimed in with agreement as she explained how they really know how to design and cut for a fuller figure, and that their pieces last (something I can personally attest to, as I have Lane Bryant pieces that are almost a decade old in my wardrobe!)
Lane Bryant’s Perfect Drape blazer is their suiting staple, with a classic cut and shapely nipped-in waist. I am also a big fan of their Bryant Blazer, which has the aesthetic effect of a double-breasted blazer without the added bulk that can sometimes happen with the double layers in front of a true double-breasted jacket. Many styles also have thoughtful details like hidden hooks to keep everything lying properly on the body. With a size range up to 40 that runs true to size, it is also a great option for any plus size shoppers looking for more affordable blazer options, both casual and workwear.
Reformation
There’s just something about a good leather blazer that is almost transformative. You put it on and instantly feel cooler. It can give any outfit a bit of edge, and is a great way to add a fun twist to an otherwise basic look. But all leather blazers are not created equal, so getting one that will wear well and only get better with time just makes sense if you are investing in a genuine leather piece.
My top recommendation for leather jackets in general is always Veda, a cool woman owned NYC label that makes the most stunning pieces, with dreamy nappa leather featuring prominently in their selection. I have (and adore) their cropped Baby Jane Moto jacket in that same leather, and I get compliments and people pretty much petting the butter soft leather whenever I wear it. So if I was buying myself a leather blazer, this nappa leather option from Veda would be it. It is available in both straight and plus sizes at Reformation, which also provides details about the sourcing of the leather, something I really appreciate.
