Blazers are everywhere right now, but figuring out what to wear underneath can feel tricky. You want something that looks put-together without being too formal or predictable.
The good news is that your options go way beyond basic tanks and boring blouses. From casual tees to elegant silk pieces, there are tons of ways to style a blazer that feel fresh, comfortable, and totally you.
1. A Classic White T-Shirt
Nothing beats the effortless cool of a white tee paired with a blazer.
This combination walks the line between casual and polished perfectly, making it ideal for coffee meetings, creative workplaces, or weekend brunches.
The key here is choosing a tee with some weight to it—think structured cotton rather than something thin and see-through.
A quality white t-shirt should hold its shape and sit smoothly under your blazer without bunching or wrinkling.
Look for one with a slightly higher neckline that won’t peek out awkwardly.
This pairing works with jeans, trousers, or even a midi skirt.
The beauty of this look is its versatility and timelessness.
You can dress it up with statement jewelry or keep it minimal for a clean, modern vibe.
2. A Silk or Satin Camisole
Want to add instant elegance to your blazer?
Slip on a silk or satin camisole.
The subtle sheen catches light beautifully and gives your outfit a refined, luxurious feel without trying too hard.
These work wonderfully for office presentations, dinner dates, or any time you want to look a little more dressed up.
Silk drapes beautifully against your skin and creates a smooth silhouette under structured jackets.
Choose neutrals like ivory, blush, or black for maximum versatility, or try jewel tones for something bolder.
The lightweight fabric won’t add bulk, which keeps your blazer sitting perfectly on your shoulders.
Pair this combination with tailored pants or a pencil skirt for a sophisticated ensemble that transitions seamlessly from day to night.
3. A Fitted Turtleneck
Turtlenecks bring an undeniably sleek, streamlined look to any blazer pairing.
This combination screams sophistication and works especially well during cooler months when you need that extra layer of warmth.
The high neckline creates a clean vertical line that elongates your torso and looks incredibly polished.
Choose a fitted style rather than something bulky—you want it to hug your body without adding unnecessary volume under your jacket.
Fine-knit materials work best because they lay flat and smooth.
Black is classic, but don’t overlook rich colors like burgundy, forest green, or navy for added depth.
This pairing looks fantastic with high-waisted trousers or a structured skirt.
Add a simple necklace or let the turtleneck speak for itself with minimal accessories for maximum impact.
4. A Crisp Button-Down Shirt
There’s something undeniably sharp about pairing a button-down with a blazer.
This menswear-inspired combination exudes confidence and professionalism while still feeling approachable.
The beauty lies in how you style it—buttoned all the way up for a traditional look, or with a few buttons undone for something more relaxed.
Try a slightly oversized fit for a contemporary twist that feels less stuffy and more fashion-forward.
White and light blue are timeless choices, but striped or patterned shirts add visual interest without overwhelming your outfit.
Make sure the collar sits neatly inside or outside your blazer lapels, not awkwardly bunched up.
This classic pairing works with virtually any bottom—jeans for casual Fridays, dress pants for important meetings, or even leather pants for an edgier vibe that still maintains polish.
5. A Knit Tank
Knit tanks offer structure without the bulk that heavier tops can bring.
Ribbed styles especially create subtle texture and visual interest while maintaining that streamlined silhouette you want under a blazer.
These are perfect for transitional weather when full sleeves feel like too much but you still want coverage.
Fine-gauge knits sit smoothly against your body and won’t create lumps or bumps under your jacket.
They’re dressy enough for work but comfortable enough to wear all day without feeling restricted.
Neutrals like cream, gray, and black are wardrobe staples, but jewel tones can add unexpected pops of color.
Pair a knit tank with wide-leg trousers for a balanced silhouette, or tuck it into a high-waisted skirt for a feminine touch that still feels modern and fresh.
6. A Bodysuit
Bodysuits solve one of fashion’s most annoying problems: the constant need to retuck your shirt.
Once you snap it on, you’re set for the entire day with zero bunching, riding up, or awkward gaps.
This makes them perfect for busy days when you don’t want to worry about your outfit shifting around.
The smooth, tucked-in look creates incredibly clean lines under a blazer.
Choose styles with modest necklines for work or something more daring for evenings out.
They come in every fabric imaginable—cotton for casual days, jersey for comfort, or even lace for something special.
Pair with high-waisted pants or skirts to show off that perfectly tucked silhouette.
The seamless look makes your entire outfit appear more intentional and put-together with minimal effort required.
7. A Striped Breton Top
Stripes instantly add visual interest to what might otherwise be a plain outfit.
A Breton top—those classic French sailor stripes—brings a casual yet chic element that feels effortlessly stylish.
This combination walks that perfect line between polished and approachable, making it great for creative workplaces or weekend outings.
The horizontal stripes create movement and break up solid colors in an outfit that might otherwise feel too monochrome.
Navy and white is the traditional choice, but you’ll find versions in black and white, red and white, or even more unexpected color combinations.
Three-quarter sleeves are especially flattering under blazers.
This pairing works beautifully with dark denim or black pants for a Parisian-inspired look that never goes out of style.
Keep accessories simple to let the stripes do the talking.
8. A Lightweight Sweater
When temperatures drop, a lightweight sweater becomes your best friend under a blazer.
Thin merino wool or cashmere provides warmth without adding unnecessary bulk that makes your jacket feel tight or uncomfortable.
This combination keeps you cozy while maintaining that tailored, professional appearance.
The key word here is lightweight—chunky knits will create too much volume and ruin the sleek lines of your blazer.
Look for fine-gauge sweaters that drape smoothly and don’t bunch at the shoulders or arms.
Crew necks and V-necks both work wonderfully, depending on your personal preference and the blazer’s neckline.
Neutral colors like gray, camel, and navy are incredibly versatile, but soft pastels or rich jewel tones can add personality.
This pairing works perfectly for chilly office days or outdoor meetings when you need practical warmth with style.
9. A Graphic Tee
Who says blazers have to be serious?
Pairing one with a graphic tee immediately adds personality and shows you don’t take fashion rules too literally.
This high-low mix creates an interesting contrast that feels current and fashion-forward.
Band tees, vintage logos, or artistic prints all work beautifully for this unexpected combination.
The structured blazer elevates what might otherwise be a casual outfit, while the graphic tee keeps things from feeling too stuffy or corporate.
This balance makes the look perfect for creative industries, casual Fridays, or weekend events where you want to look pulled-together but still relaxed.
Keep the rest of your outfit relatively simple—solid-colored pants or jeans work best so your graphic tee remains the focal point.
This pairing proves that blazers can be fun, not just formal.
10. A Lace or Sheer Blouse
For occasions that call for something more dressed up, a lace or sheer blouse brings instant sophistication and femininity.
These delicate fabrics add texture and visual interest while maintaining an elegant, refined appearance.
The contrast between the soft, romantic blouse and structured blazer creates a beautifully balanced outfit.
Choose styles with enough coverage or wear a camisole underneath if the sheerness feels too revealing for your comfort level.
Black lace is timelessly chic, while ivory or blush tones offer a softer, more romantic vibe.
Details like scalloped edges or floral patterns add extra charm.
This combination works wonderfully for evening events, dinner dates, or holiday parties when you want to look polished but not overly formal.
Pair with tailored trousers or a sleek skirt for maximum impact that feels special.
