ISTO. Classic T-Shirt

Portuguese men’s clothing brand ISTO has taken the liberty of obsessing over every stitch of its Classic T-Shirt. Why? So you don’t have to. But also so you can show up to your next pitch meeting, wedding, or other suit-adjacent affairs in the most comfortable, functional, and stylish way possible.

Easily the overall best undershirt for white dress shirts, the Classic is constructed entirely of Portuguese organic cotton, checking the cozy box with a bullet. Elsewhere under the hood, the classic collar, slim, tailored fit, attention to detail around the shoulder stitching, and the sleeve length is evidence of ISTO’s healthy obsession with creating your next ride-or-die undershirt.

Bonus: thanks to its flattering cut, solid look and feel, and availability in 12 neutral colors, you can and should feel free to wear this beauty as a top layer as well.

Gildan Crew T-Shirts Multipack

Unlike ISTO’s Classic, Gildan’s multipack of crew tees falls firmly in line with the litany of excellent undershirts that do their job well but should never see the light of day. They’re available at a super-accessible price point, but you’ll still find that these 100% cotton tees provide ample breathability and are made to last.

Moisture-wicking properties will help keep you cool during those summer weddings or weekday coffee walks and its nine color options will play nice with most top layers. Andto put an exclamation point on the whole package, these tees have just shy of 200,000 5-star reviews on Amazon. The people have spoken and so have I. We can do no more for you and your torso. It’s in your hands now. Make us proud…

I’ll see myself out.

Closed T-Shirt

This cloud-soft, 100% Supima cotton t-shirt from German label Closed is the t-shirt’s t-shirt. The one that other tees want to be when they grow up. It shows up late to the party. It has a great hook shot. It can pan-sear a NY strip to perfection. It can… do none of those things because it’s a t-shirt. But you get the point, yes?

This would serve you well as an impossibly comfortable, beyond-adequate undershirt, of course. That part goes without saying. But on those occasions when it’s time to shed the dress shirt and relax a bit, you’ll be thankful you went with this crisp, dapper, detail-obsessed tee instead of a transparent afterthought of an undershirt. And it’s yet another outstanding option for wearing on its own with a nice pair of jeans or chinos.

Thompson Tee Sweatproof Undershirt

Calling all active sweat glands. Ew. Let me try that again.

If you tend to sweat more than the average guy, you’ll find solace in the very niche, very functional Thompson Tee Sweatproof Undershirt. Better? Better.

You see, each of these tees features super-absorbent armpit pads that are integrated into the shirt’s fabric. And since this 100% combed cotton number is strictly an undershirt, the people around you will be none the wiser. The tagless collar is designed to lay flat against your neck and Thompson Tee has thoughtfully added a bit of extra length to help keep your shirt tucked in.

What To Look For In The Best Undershirts For White Dress Shirts

Technical Details

At the end of the day, undershirts have a job to do. First and foremost, they should be comfortable. But they should also ideally incorporate functional details like sweat-wicking and odor-reducing properties, four-way stretch materials, and fabrics that won’t lose their shape over time. Bonus points for quality stitching and overall construction that’s made to last.

Color

Wearing white undershirts under your white dress shirts will help accentuate the whiteness of your top layer. It also keeps distractions to a minimum in terms of what’s visible beneath the dress shirt. Another color that will help keep your undershirt operating in the background is light gray.

Material

Cotton is king when it comes to the best undershirt for white dress shirts. It’s a lightweight, comfortable fabric that’s both breathable and durable. Most quality undershirts also incorporate a small percentage of elastane to expand your range of motion. Generalities aside, always go with what feels the best on your body and what looks the best under your dress shirts.
