What To Wear Under A Blazer – Women’s Guide

If you’re reading this, then you probably already know the value of a good blazer. They’re an essential part of any office wardrobe and can be worn in nearly any situation. But what if you don’t have the right top to go under it?

What To Wear Under A Blazer

Or worse yet, what if your layering game is off? Never fear! I’ve got all the answers here. From turtlenecks to button-down shirts, I’ve rounded up my favorite options to help you find exactly what works best with your blazer (and everything else).

When choosing what to wear under a blazer, there are several factors to consider

  • The first thing you want to consider when choosing an undergarment is how it will complement your blazer

A basic rule of thumb is that you want the color, texture, and style of your undergarments to be complementary to your blazer’s color, texture, and style.

So if you’re wearing a solid-colored blazer, choose something also solid-colored. The same goes for patterns like stripes or plaids – stick to one type of pattern per outfit.

  • The second thing worth considering when choosing what kind of underwear to wear underneath your blazer is the fabric type

Don’t wear anything too tight since it will show through on top! And don’t go too loose either because it could bunch up awkwardly underneath your clothes and make everything feel unkempt (not cute).

  • The Season

When choosing an undershirt for your blazer, it’s important to consider what season it is and what kind of climate you’ll be in when wearing your suit in public.

For example, if you live in a tropical climate where temperatures are regularly around 80 degrees Fahrenheit or above, wearing a thin cotton t-shirt under your blazer may be too hot for comfort — especially in an air-conditioned restaurant or office building where

  • The occasion

Is this event formal or informal? It would help if you chose an undershirt that matches the level of formality at the event — think slinky tops for cocktail parties and more conservative options for business meetings and interviews.

  • Your body type

There are several different body types, and each has challenges when it comes to finding the right foundation garments.

For example, wearing a full slip under your dress will help smooth out any lumps and bumps if you have an hourglass shape. If you’re pear-shaped and have wide hips, but narrow shoulders, wearing a bodysuit will create seamless lines under your blazer while creating curves at the waist.

  • Your style

Do you like showing off your curves or prefer more coverage? Your undershirt should reflect your style.

  • The Cut of Your Blazer

There are two main types of blazers: single-breasted and double-breasted. Single-breasted jackets have one row of buttons on the front (usually one or two pockets on the chest).

Double-breasted blazers have two rows of buttons (usually three or four total). While double-breasted blazers can be worn year-round, single-breasted jackets are more versatile because they don’t require you to layer up as much as double-breasted styles during winter.

Single-breasted blazers can also be worn with jeans, khakis, and dress pants.

Ten best under-blazer clothing items

Wear a camisole under your blazer

A camisole is a type of undergarment that can be worn alone or underneath clothing. It’s often made from lace, silk, or cotton and can be closed at the front with buttons, hooks, or zippers.

Camisoles are close-fitting, creating an even layer between your skin and whatever top you wear over them.

They’re also good at absorbing sweat while protecting sensitive areas such as the stomach, back, and chest from irritation caused by rubbing against other materials in your closet.

Pair a tank top with your blazer

A simple tank top is an excellent option for layering under a blazer. It’s lightweight so that it won’t add extra bulk under your jacket, and it also comes in many styles that can help you change your look every day if needed.

Plus, tanks are easy to find at any store, so you won’t have trouble finding one that works for you!

Fitted v-necks

A v-neck top is one of the easiest ways to add an extra layer of warmth under a blazer. It also provides more coverage than a crew neck, which can help if you have a long torso or are wearing a short blazer.

If the top has short sleeves, this is also the time to break out the cardigan or bolero jacket —make sure it’s not too bulky and doesn’t overwhelm your outfit.


The turtleneck is a winter wardrobe essential for all women. It’s versatile, as it can be dressed up or down, and keeps you warm and cozy during the cold months.

In addition to being an easy way to look put-together, turtlenecks are flattering on everyone. They create a slimming effect on the neckline and elongate the neck, so if you have a short neckline or a long torso, this will help balance your proportions.

You can wear turtlenecks with anything from blazers to dresses —make sure you pair them with pieces that match in color and texture.

For example, if you’re wearing a black turtleneck with black pants, try wearing another neutral-colored top like gray or navy blue underneath your blazer.

The best thing about turtlenecks is that they come in so many different styles that there’s one for every woman out there!

If you’re looking for something simple yet stylish, try wearing a ribbed turtleneck underneath your blazer with high-waisted jeans, leggings, and ankle boots.

If you want something more chic and sophisticated, go for a silky sleeveless tee with a bowtie neckline underneath your blazer with skinny pants and knee-high boots.


A button-down blouse or a shirt in a subtle print can be worn under a blazer to add dimension and interest to your outfit.

Make sure that whatever you choose has enough structure, so it doesn’t bunch up around the neckline of your jacket when you sit down.

Button-down blouses with collars that are visible when you stand up give a polished look and will help keep your neckline covered when sitting down or bending over.

A solid-color long-sleeved top that hits at the hip can also work well with a blazer —make sure it doesn’t go past your hips, so it doesn’t bunch up around the waistband of your skirt or pants.

Graphic tees

If you’re wearing a blazer with a graphic tee, don’t be afraid to show off your sense of style. Try pairing a blazer with a graphic tee and wear it with jeans or shorts for a fun and casual look.

Polo shirts

When it comes to the perfect blazer, you want something that will make you feel confident and professional. So what should you wear underneath your blazer? The answer is simple: a polo shirt!

Polo shirts are the perfect way to layer under a blazer because they’re comfortable and flattering.

They will help keep you cool and comfortable, especially if you have long days at work or are in an air-conditioned office all day. They also look great with any outfit, from skirts or pants to jeans or shorts.

Polo shirts come in so many different styles, colors, and patterns that it’s easy to find one that fits your style perfectly. Plus, these shirts are so versatile that they can be worn year-round — from summer through fall and winter into spring!

Polo shirts are also super affordable, so there’s no reason not to stock up on them!

Sheer tops

Sheer tops can be worn under a blazer, but they shouldn’t be too revealing. Make sure that you choose an appropriate top to wear under your blazer.

You’ll also want to ensure that the sleeves are long enough to cover up any skin when you take off your jacket.


A sweater is a great addition to your wardrobe, especially in the colder months. It’s an easy way to add warmth to an outfit while still looking put-together, and it can also be a great layering piece under a jacket or blazer. Choose from various colors, textures, and patterns to find the perfect one for you.

Lace tops

Lace tops are perfect for wearing under blazers because they add an element of femininity that can be lost with other fabrics like denim and flannel.

They also help break up the solid color of your blazer so it doesn’t look too uniform from head to toe.

Final Thoughts

The blazer is a wardrobe staple that will never go out of style. It’s perfect for work, but you should also know that you can wear it in your everyday life as well.

You don’t have to wear a blazer with matching pants or skirt—you can dress it up with a camisole or tank top underneath, tuck in your shirt and pair the look with pants or jeans.

You can also try pairing up your favorite sweater vest over this blazer if you want to add some texture to the mix!
