10 Best Men’s Undershirts for Dress Shirts

Selecting the right undershirt as a base layer for a dress shirt, suit or tuxedo seems like a simple decision. After all, it’s just a shirt… right?

Well, with all of the options, colors, styles and fabrics available on the market, choosing an undershirt for dress shirt is a difficult choice – much less choosing the best undershirt. Pick the right one and you’ll feel comfortable, confident and ready to tackle any occasion; pick the wrong one and you might become an uncomfortable, sweaty mess.

Here are some must-know tips and tricks on how to pick the right undershirt for special occasions as well as 10 of the best men's undershirts for dress shirts.

Why Wear an Undershirt Under a Dress Shirt

Wearing an undershirt under a dress shirt is strongly recommended, and the reason is threefold:

1. They protect your dress shirt from deodorant and sweat stains. As you go about your day, your body naturally produces sweat and oils that can rub onto your dress shirt. This can lead to yellowing, discoloration and unpleasant odors over time. An undershirt acts as a barrier between your skin and your outer layer, keeping you and your dress shirt fresh.
2. They help smooth out any bumps or lumps under your dress shirt, creating a smoother, more polished appearance. This can be especially useful if you have certain body features that you’d prefer to keep hidden.
3. They keep you comfortable and warm under lightweight dress shirts. Even if you have a thick dress shirt, it may not provide enough insulation on its own to keep you warm in chilly temperatures. Wearing an undershirt can help your body maintain heat, keeping you warm and comfortable no matter the occasion.

Aren’t Undershirts and T-Shirts The Same Thing?

Both undershirts and t-shirts can be worn underneath outer layers of clothing – but there are some key differences between the two.

One of the main differences between undershirts and t-shirts is the fit. Undershirts are designed to be worn under other clothing (like dress shirts), so they tend to be form-fitting and slim. T-shirts, on the other hand, are looser and have a more relaxed fit.

Another key difference is the fabric. Undershirts are typically made from lightweight, moisture-wicking materials like cotton or a blend of synthetic fabrics. T-shirts are made from a wider range of materials, including cotton, polyester, rayon or blends.

Although it’s tempting to throw on your favorite tee under a dress shirt, don’t do it – especially a graphic tee. It may add unnecessary bulk, and it will likely be visible underneath your dress shirt.

Tips to Find the Best Undershirts for Dress Shirts

Here are a few must-know tips to help you find the perfect undershirt to wear under a dress shirt:

• Consider the fit. The undershirt should be snug enough to stay in place and not bunch up under your dress shirt but not so tight that it's uncomfortable or restrictive. Look for undershirts labeled "slim fit" or "tailored fit" for a closer, more streamlined fit.
• Choose the right material. Cotton is a popular choice because it's soft, breathable, and absorbs moisture well. Synthetic materials like polyester and nylon can also be effective, as they wick away moisture and dry quickly. Just be sure to avoid materials that are too thick or heavy (like wool), as they may be noticeable under your dress shirt.
• Be mindful of the neckline. A crew neck undershirt is a classic choice that works well under most dress shirts. However, if you prefer a more streamlined look, a V-neck undershirt can be a good option. Just be sure to choose one that's not too high, as it could be visible under your dress shirt.
• Pay attention to the length. If the undershirt is too long, it may bunch up or peek out from under your dress shirt. On the other hand, if it's too short, it may ride up and cause discomfort.
• Look for moisture-wicking and anti-odor labels. Consider choosing undershirts with these features to help keep you feeling fresh, dry and confident no matter the occasion.

Uniqlo

Uniqlo’s AIRism undershirt is designed with performance fabric that’s meant to wick sweat away from your body to keep your skin dry and comfortable.

It’s also lightweight, breathable and quick-drying, making this a wardrobe essential in warmer months.

RibbedTee

RibbedTee’s EVO TENCEL V-Neck Undershirt is the ultimate v-neck undershirt. It features an extra-low neckline, making this a great option if you want to ensure that your undershirt remains hidden underneath your dress shirt. However, v-necks aren’t a good option only because they’ll hide behind your dress shirt – they’re also great for those who want to appear taller or create the illusion of a longer neck. The EVO TENCEL also has a longer back tail, which helps keep it comfortably tucked.
