A blazer is one of the most versatile pieces in any wardrobe, seamlessly transitioning from casual to professional settings. Blazers have been a huge trend this year, but they are also so timeless that I don’t consider them “trendy.” But finding the right thing to wear under a blazer can be tricky – too formal, and it might feel stiff; too casual, and it could ruin the polished effect. Whether you’re dressing for a job interview, a smart-casual look, or just running errands and want to look chic, this guide has you covered with 10 outfit ideas for pairing the perfect blazer with tops that fit every occasion.
What To Wear Under A Blazer (+ 10 Outfit Ideas For Every Occasion)
1. Button-Up Shirt
For a polished and professional vibe, you can’t go wrong with a button-up shirt under a blazer. Whether you choose a neutral color or a pop of print, this combination works for the office, meetings, and formal events.
The button-up shirt is a go-to option for its versatility and ability to pair seamlessly with both fitted and oversized blazers.
2. Silk Blouse
A silk blouse adds a touch of elegance to your blazer outfit. Its smooth texture contrasts beautifully with structured blazers, making it ideal for business dinners, parties, or date nights.
- Pair a silk blouse like this silky peasant blouse with an oversized blazer and jeans for a chic yet laid-back look.
- Tuck it into high-waisted pants or a skirt and cinch with a belt for a flattering silhouette.
3. Fitted Turtleneck
For cooler weather, a fitted turtleneck under a blazer exudes effortless style (my favorite is this Merino Wool-Silk Sweater Tank). It’s cozy, streamlined, and versatile, working equally well for casual outings or professional settings. Here are a few style tips:
- Combine a wool blazer with a lightweight cashmere turtleneck for a stylish winter look.
- Stick to neutral colors like black, gray, or beige to keep it polished.
- Pair with leggings or slim trousers to avoid adding bulk.
I share how to style leggings with a blazer in this post.
4. Simple T-Shirt
For a relaxed, smart-casual look, a crew neck or v-neck t-shirt under a blazer is a great option. It’s perfect for coffee dates, casual Fridays, or errands with a touch of polish. I love a classic white tee like this one or a more fitted tee like this ribbed one from Nuuds.
- A plain white t-shirt or a graphic tee paired with a black blazer and jeans creates an effortlessly cool outfit.
- Opt for a fitted tee to maintain a clean silhouette or a slightly oversized t-shirt for a more laid-back vibe.
5. Camisole or Tank Top
When dressing for warmer months, a camisole or tank top is a lightweight, stylish choice under a blazer. This combo strikes the perfect balance between casual and elegant. This square neck tank bodysuit is super flattering.
- Pair a satin or lace-trim camisole with a tailored blazer for a date night look.
- A basic tank top works well for casual outfits with an oversized blazer and jeans.
6. Sweater or Knit Top
A sweater under a blazer is perfect for fall and winter, keeping you warm without sacrificing style. Opt for lightweight knits that fit snugly to avoid bulk. My favorite flattering cashmere tops are from Quince (see the rest of my favorite sweaters in this post)
- Pair a cashmere sweater with a plaid or herringbone blazer for a cozy, polished outfit.
- Choose a crew neck or v-neck sweater in a neutral color for versatility.
7. A Dress or Skirt
Pairing a blazer with a dress creates a sophisticated, fashion-forward look for various occasions, from office wear to evening outings. I wore a blazer with this fun faux suede skirt from Amazon last year and love how they looked together. My exact faux skirt is currently out of stock, but I found a suede skirt that’s a similar flattering fit!
- For the Office: Layer a tailored blazer over a simple black shift dress or A-line dress. Add heels for a professional finish.
- For a Night Out: Pair a black blazer with a fitted, silk dress and statement accessories for an edgy, elegant vibe.
- Throw an oversized blazer over a t-shirt dress or sundress with sneakers for a laid-back, chic outfit.
8. Hoodie for a Casual Edge
For an unexpected twist, layer a hoodie under your blazer for a trendy, laid-back vibe. Perfect for casual outings or errands, this pairing mixes structure with street style. I have my favorite loungewear linked in this post.
- Choose a neutral-colored hoodie for a streamlined look under an oversized blazer. I like grey best!
- Pair with jeans or leggings for ultimate comfort. This is a review of the best Amazon leggings.
- Your blazer needs to be quite oversized for this look to work!
9. Workout Onesie
For those busy days when you’re running errands or heading to the gym, layering a blazer over a workout onesie creates an effortlessly cool, athleisure-inspired look.
- Choose a sleek, monochromatic onesie for a polished effect.
- Pair with sneakers and an oversized blazer for a trendy, functional outfit.
If you’re looking for a full length workout onesie, Athleta has a great one.
10. Wear the Blazer on Its Own
For a bold, fashion-forward look, consider wearing your blazer without anything underneath. This style works best with tailored blazers that have a high enough neckline and can be comfortably buttoned without revealing too much. It’s a sleek, minimalist option that exudes confidence and elegance.
- For a night out, pair a black blazer with high-waisted trousers or a skirt for a striking ensemble. Add statement accessories to elevate the look.
- For a sophisticated twist, choose a double-breasted blazer or one with unique details, such as gold buttons or an asymmetric design, for added flair.
- Make sure the blazer fits perfectly and provides enough coverage to feel comfortable and secure.
This no-shirt-under-blazer look is daring yet polished, perfect for making a statement at an event or night out.
Tips for Pairing Tops with Blazers
When styling your blazer outfits, keep these tips in mind:
Choose the Right Fabric
Match heavier blazers with lightweight tops to avoid bulk, and pair lighter blazers with more substantial fabrics like knits.
Find the Perfect Fit
An oversized blazer works well for casual looks, while a tailored blazer is better for formal occasions.
Accessorize Smartly
Add belts, jewelry, or hats to make styling look intentional, especially when going for an unconventional shirt under a blazer, like a graphic tee or skipping the shirt altogether.
The best blazers for all occasions
I need to share my favorite blazers. While this list isn’t comprehensive, these are my current favorites (and pretty affordable, actually). The first two are the two I own and wear often, the rest are wishlist items.
The Drop Blake Long Blazer
This is from Amazon, and I own it in two colors. The Drop is known for high-quality items, and I’ve loved the Blake Blazer for almost two years now. The length covers my bottom which makes it perfect for leggings, but it’s not oversized, so I find it really flattering on my petite frame. I wear a size XS.
Juliette Check Double Breasted Blazer
This Juliette Check Double Breasted Blazer from Petal and Pup is my other favorite blazer these days. The plaid pattern is fun but still neutral, and the double-breasted detail makes it really chic. It has a slightly relaxed look to it – less tailored than the Blake blazer, but it would still work in an office setting. Size up if you’re between sizes.
Ann Taylor Madison Blazer in Plaid
The Madison Blazer in Plaid is one of my very favorites I recently got (and it’s actually the one I’m wearing at the top of this post). The fit is tailored without feeling too structured since the cut is rounded a bit, and the plaid gives it that classic, polished vibe I always look for in a blazer. It’s perfect with jeans and a tee or a dress for something a little more dressed up.
Tuckernuck Navy Diana Blazer
I’ve been eyeing the Navy Diana Blazer for a little while, and since I don’t currently own a navy blazer, I think I’m going to order it. I love that it has an oversized double-breasted silhouette and gold buttons. It would be perfect with light-wash jeans and gold accessories.
Amazon Tweed Blazer
This is another blazer that I’ve had my eye on for a while but haven’t gotten around to ordering! It’s affordable and shipping is free on Prime, so there’s really no excuse. I love the idea of pairing a light-colored tweed blazer with spring outfits as we get closer to warmer weather.
What Not to Wear Under a Blazer
There are a few styles of tops that don’t look as polished under a blazer. Avoid wearing thick knit sweaters, as they add unnecessary bulk and can make the blazer feel tight and restrictive. Tunic shirts are also a poor choice since their long, flowy hem often extends awkwardly beyond the blazer. Similarly, cowl necks can compete with the blazer’s neckline, adding too much volume around the chest and making layering appear messy rather than refined.
Final Thoughts
From classic button-down shirts to trendy hoodies and dresses, there are countless ways to style a blazer for any occasion. By mixing and matching tops with your blazer, you can create outfits that range from casual to professional while showcasing your personal style.
