What Is a Blazer?

A blazer is the effortlessly chic cousin of the suit jacket, bringing a sophisticated vibe without the “strictly business” attitude. What makes it a closet must-have? Well, for starters, durability is its middle name – often made of strong yet breathable linen, cotton or cozy wool. Often featuring buttons and pockets, they aren’t just practical but ultra-stylish too. 

There are two main players in the blazer world – you’ve got single-breasted, where the jacket closes with one row of buttons, while a double-breasted blazer brings more flair with overlapping front panels and extra buttons. Lapels and sleeves play their part too, with options like notch, peak, shawl and full-length or rolled up. Colors? The palette is as diverse as your Insta feed. From muted tones to bold statements, there’s a blazer to match your mood. 

Blazers are the OG timeless pieces that can be as structured as your Monday morning meeting or as chill as your weekend plans. So, whether you’re conquering the workweek hustle or elevating your Sunday brunch look, a blazer is your stylish sidekick, promising a perfect mix of class and comfort.

How Should a Blazer Fit?

Now, let’s talk fit – because when it comes to blazers, nailing the perfect fit is the key to fully learning how to style a blazer. The details that you should pay attention to when choosing one include the sleeves, lapels, shoulder seams, cut and hemline.

Sleeve Length

Your blazer sleeves should fall right between your wrist and thumb joint. Why this sweet spot? Well, it’s about that perfect balance – long enough to exude elegance, yet short enough to avoid drowning in fabric. The goal is to strike a spot where your sleeves seamlessly complement your hand movements, making your ensemble look curated and intentional.


Lapels, the front panels on your blazer, also play a role in how to style a blazer. They should sit snugly against your chest, covering about half of your breasts when buttoned. Minimal pulling or bunching is the goal here, though – your blazer should embrace you, not constrict you! While lapels might not have a huge impact on fit, they’re your chance to express your unique style. From angular notch and peak lapels to softer shawl lapels (or no lapels at all!) embrace a look that resonates with you.

Shoulder Seams

Well-positioned shoulder seams are the backbone of a great blazer. They should comfortably sit at the top of your shoulders, creating a line that complements your body shape. Here’s a test – raise your arms above your head. If the shoulders feel tight, consider sizing up. If the seam hangs off your shoulder when you’re standing straight, a smaller size might be the answer. This doesn’t have to be the rule though, as boyfriend blazers have a purposefully oversized look for a more relaxed feel. Achieving a perfect fit in the shoulders ensures a comfortable range of motion without sacrificing the structure that makes blazers iconic.


Cut defines your blazer’s overall look. They can have a straight, oversized cut for a relaxed feel, but if you’re aiming for a more feminine silhouette, try one that nips in at the waist. The tailored approach not only flatters your figure but also adds a touch of sophistication to your ensemble. Whether you’re heading to an office holiday party or a stylish night out, the right cut can transform your blazer from basic to bombshell.


Hemlines – the final touch that ties your blazer together. The sweet spot is right where your hips and legs meet. Though blazers can be cropped or oversized, with straight-cut or rounded hems, this versatile, go-to length complements a variety of body types and offers timeless appeal.

In mastering the art of how to style a blazer, it’s not just about conforming to trends – it’s about embracing the details that make it uniquely yours! So, next time you slip one on, pay attention to the sleeves, lapels, shoulders, cut and hemlines – because a well-fitted blazer is your ticket to zero-stress style.

Blazers aren’t just for dressy occasions – they bring structure and style points to your daily outfits.

Effortlessly Chic: Casual Blazer, Midi Skirt, or Dress

The key here is the mix of textures, which creates a dynamic and eye-catching “quiet luxury” look that easily transitions from day to night.

Off-Duty Chic: Casual Blazer, Graphic Tee, Jeans or Leggings

When the mood is off-duty yet chic, rock a casual blazer with graphic tees and jeans or leggings. It’s the everyday look that’s equal parts stylish and comfortable! The blazer is an unexpectedly edgy statement piece, but the tee keeps it relaxed. Paired with black jeans, you’re the epitome of off-duty cool. This ensemble is perfect for conquering errands, grabbing coffee with friends or simply unwinding in style. It’s proof that you can rock this look even on your most relaxed days.

Great for professional settings, the black-on-black says bold confidence, making it perfect for a high-stakes meeting or a dressier event. You can play around with patterns and colors when choosing a blazer. Stripes, bold florals and classic neutrals are versatile choices and prove that sometimes simplicity is the key to stunning style.

This combo mixes personality and luxurious textures, showcasing your unique taste while maintaining a dressy feel. It’s a delightful departure from the conventional, perfect for nights out, dates or business events. Adding a touch of playfulness to your dressy outfits is always a good idea.

Trendy Tailoring: Matching Blazer and High-Waisted Trousers

Enter the world of trendy tailoring with a matching blazer and high-waisted trousers! Matching or tonal colors between the jacket and pants keep things put together, but feel free to experiment with fun colors for your first layer. This look gives a modern twist to traditional suiting – the blazer emphasizes the waist while high-rise pants elongate the legs. It’s a preppy look that goes from meetings to networking events, ensuring you stand out with confidence.
