Wearing an undershirt can help extend the life of your white dress shirts, providing an extra barrier against sweat stains and saving you money in the long run. The best undershirts for white dress shirts fit close to the body and are made of breathable, lightweight fabrics that absorb or wick away moisture, such as cotton, rayon, or modal. They come in sleeveless and short-sleeved designs, in scoop-neck, V-neck, and crew-neck options.

What to consider when shopping for the best undershirts for white dress shirts


  • Cotton and cotton blends: Lightweight and soft, cotton has great absorbency and breathability. Some cotton options are blended with polyester, resulting in a fabric that wicks away moisture without trapping heat, while others feature a jersey-knit construction for an even softer, lived-in feel. Note that ribbed cotton will be stretchier and more formfitting — a style that works well under slim-cut button-downs — while non-ribbed styles will offer a looser feel throughout. Cotton undershirts also tend to be budget-friendly, frequently sold in cost-effective multipacks.
  • Bamboo rayon: Boasting excellent breathability and moisture-wicking properties, bamboo helps manage sweat and makes for a great cooling shirt. It’s often combined with spandex or elastane, giving it a stretchy, body-hugging quality. Bamboo undershirts tend to be on the more expensive side, but their cooling abilities may be worth it for some.
  • Modal: Durable and more absorbent than cotton, modal tends to have a silky, second-skin feel, especially when combined with a stretchy material like elastane or spandex. Like rayon, modal shirts have a higher price point than cotton or cotton blends, but they have a luxe feel that some people prefer.

Neck cut

A basic crew-neck top works well if you’re planning on wearing your dress shirt buttoned up with a tie. If you want the option of unbuttoning your dress shirt while keeping your undershirt hidden, though, a scoop neck or V-neck will be your best bet.

Sleeve length

Sleeveless tank-style undershirts are great for warmer weather, but those concerned about sweat might want to consider a short-sleeved undershirt, as the extra fabric creates an absorbent barrier between your underarms and your dress shirt. There’s even a sweat-resistant shirt on this list that has built in pads to absorb perspiration, so it won’t show up on your outer shirt.

With all that in mind, these are the best undershirts for white dress shirts, so you can clean up nice in the most comfortable way possible.

According to a reviewer: “I don’t like my t-shirts very loose so these are perfect as they fit close to my body. These shirts also come down below the belt area which makes them easy to tuck in. These t-shirts are a great value as well. I will be purchasing more.”

6. The modal crew-neck


  • 4.3-star overall rating on Amazon, 1,100+ reviews
  • Stretchy, body-hugging fit
  • Short sleeves create sweat barrier

One reviewer wrote that these crew-neck Calvin Klein undershirts are “a step up from a regular undershirt both in wicking ability and comfort,” which just might make it worth the higher price. Made from silky soft modal, this shirt is absorbent and blended with elastane for an ultra-stretchy and thin fit that’s virtually undetectable under your dress shirt. Because of the higher neckline, this tag-free shirt is best worn under fully buttoned shirts.

According to a reviewer: “It is clingy and thin, with flat seams, which is perfect for an undershirt. The modal material is extremely soft and stretchy, forming to the body without feeling tight at all. It breathes, so it vanishes under a button-down in both how it feels and how it looks (no chunky lines).”

  • Available sizes: Small — X-Large

7. The V-neck with underarm sweat pads


  • 4.6-star overall rating on Amazon, 2,100+ reviews
  • Built-in underarm sweat pads

If you’re looking to manage moisture, this V-neck with built-in, absorbent underarm pads is one of the best undershirts for sweat. Made from cooling bamboo rayon and stretchy spandex, this undershirt works to keep you dry and prevent sweat stains on your dress shirt. The tag-free shirt has a tailored fit, and even though the pads are absorbent, many reviewers noted that they don’t feel bulky under clothes. This V-neck tee may have a higher price point than the other options, but it may be worth it for those who want to make staying dry a priority.

According to a reviewer: “Alright, if you’ve been agonizing over the cost of these, let me just tell you it’s worth it! I am [cheap] when it comes to clothes, but if you sweat a lot (and I do mean A LOT) this shirt works and it’s money well spent! Seriously 12 hour days and high stress situations and not a stitch of sweat shows through! I normally have pit stains showing through in less than an hour.”
