Blazertje: Your New Favorite Jacket for 2025

Wondering what a blazertje is and why everyone’s wearing one? Here’s everything you need to know – from styling ideas to the best places to buy one under €150. You’re scrolling Instagram on a Monday morning, coffee in hand, and you see her again: the girl who somehow looks put-together but still comfy in that soft, slightly oversized jacket. You zoom in. The caption says “blazertje season.” You’ve seen the word everywhere lately, but what exactly is a blazertje? Don’t worry – I was confused too until I bought my first one last spring. Now I own three and basically live in them. Let me save you months of research.

Things You’ll Know After Reading This

A blazertje is just a lighter, comfier version of a normal blazer.
One good blazertje can replace half your jackets.
You can find great ones from €45 to €150 if you know where to look.
They work on every body type (yes, even petite and plus-size).
2025 is the year of the oversized linen blazertje – and I’ll show you how to wear it without looking like you borrowed your dad’s suit.

What Exactly Is a Blazertje?

Think of it as the chill cousin of the classic blazer. A regular blazer is stiff, lined, and screams “job interview.” A blazertje is soft, usually unlined or half-lined, and feels like a hug you can wear to the office or brunch.

Here’s the quick difference:

Classic blazer: structured shoulders, heavy lining, formal vibe
Blazertje: relaxed fit, lightweight fabric, looks good with jeans or pajamas (okay, almost)

The word comes from Dutch – “blazer” + “tje” (little). The Dutch have been wearing these forever, and now the rest of us finally caught up.

Why Blazertjes Took Over in 2025

Remember when we all went back to the office after working from home and nobody wanted to wear stiff suits anymore? That’s when the blazertje became a hero. Searches for “smart-casual jacket” went up 40% since 2023, and honestly, I get it. I wore mine to a client meeting over a white tee and felt like the coolest person in the room.

Scandinavian influencers like Matilda Djerf and Dutch brands made them famous on TikTok. Suddenly everyone wanted that effortless “I woke up like this but still have my life together” look.

2025 Blazertje Trends You’ll See Everywhere

Oversized everything – think boyfriend fit, but better
Cropped versions that look amazing on shorter girls
Linen and linen blends for summer (finally something that doesn’t make you sweat)
Pinstripes are back, but softer
Pastel colors – especially sage green and butter yellow
More plus-size and gender-neutral options than ever

My personal favorite right now? The creamy beige oversized linen blazertje. It goes with literally everything.

How to Pick One That Actually Fits You

I learned this the hard way after buying one that pulled across my chest. Here’s what I wish someone told me:

Shoulders are the most important part – they should sit exactly on your actual shoulders
Size up if you’re between sizes (trust me)
Curvy? Look for darts or wrap-style belts
Petite? Cropped or slightly nipped-in waists stop you drowning in fabric
Plus-size? Brands like ARKET and Eloquii go up to 4XL and actually fit

For summer, stick to linen or Tencel. For winter, go for wool blends you can layer.

10 Real Ways I Style My Blazertjes

Wide jeans + loafers + white tee (my weekend uniform)
Slip dress + strappy sandals (instant evening look)
Hoodie underneath (yes, really – Gen Z taught me this)
Matching trousers for that expensive-looking suit set
Bike shorts + tank top (controversial but so comfy)
Over a swimsuit as a beach cover-up
With a turtleneck and long wool coat in winter
Belted with a midi skirt for date night
Thrown over gym clothes when you’re late
Pajamas (don’t judge me, we’ve all done it)

The Problems People Have (and How to Fix Them)

“My blazertje pulls at the buttons” → Size up or look for stretch fabric. Unlined ones never do this.

“It looks too boxy on my short frame” → Try cropped styles or add a thin belt. Instant waist.

“It wrinkles like crazy” → Linen wrinkles (that’s the look), but linen-cotton blends stay smoother.

“I overheat in anything with sleeves” → Pure linen or Tencel. I lived in mine during a 35°C heatwave.

“Plus-size options are ugly” → Not anymore. ARKET, Eloquii, and Universal Standard have gorgeous ones.

Blazertje vs Regular Blazer – Which Do You Need?

Quick test:

Do you have job interviews or very corporate offices? → Keep one classic blazer
Do you live in jeans and want to look polished? → Blazertje all the way

Most women I know have one proper blazer gathering dust and wear their blazertjes daily.

So, Is a Blazertje Worth Buying?

Start simple: grab a beige or black oversized one under €150. Wear it with what you have on right now. I promise you’ll understand the hype in about five minutes.

Frequently Asked Questions

What exactly is a blazertje?

Hey, a blazertje is basically a chic, lightweight blazer—think of it as the casual Dutch cousin of the classic suit jacket. It’s tailored but relaxed, perfect for adding polish without the stuffiness, and it originated from sporty uniforms in the 1800s. Grab one in navy for endless versatility!

Is the blazertje formal or casual?

It’s your go-to for that sweet spot between formal and casual—super adaptable! Dress it up with slacks for meetings or down with jeans for brunch. The key? Softer fabrics lean casual, while structured wool amps up the polish. You’ll nail any vibe effortlessly.

What fabrics work best year-round?

For all-season ease, go for breathable cotton blends or wool mixes—they’re comfy in heat and layer well in chill. Linen shines for summer lightness, while tweed adds cozy texture for fall. Pick versatile neutrals to mix and match without overthinking your closet.

Can anyone wear a blazertje?

Absolutely, it’s made for everyone! Whether you’re petite, curvy, tall, or anywhere in between, the right fit flatters all. Pair it with jeans for casual days or chinos for work—its relaxed vibe boosts confidence without trying too hard. Just tailor for that personal touch.

Where should I buy a sustainable blazertje?

Look for eco-brands using organic cotton or recycled fabrics—they’re game-changers for guilt-free style. Thrift spots offer unique vintage gems, or check online for certified options like GOTS-approved pieces. It’s easy to score timeless quality that lasts seasons.

How do I style a blazertje if I’m petite?

As a petite pal, opt for hip-length cuts to elongate your legs—pair with high-waisted pants or cropped tops for balance. Single-breasted styles hug without overwhelming; roll sleeves for a fun twist. Heels or loafers add height, making you feel tall and fierce!
