Man here. Always. I can’t stand the feel of a button-up or polo without a undershirt on.
I picked “let me explain.” If you’ve never visited NH between New Years and Saint Patrick’s day, let me assure you that it’s really freaking cold. I hate being cold. People tell you “wear layers,” but I hate wearing layers almost as much as I hate being cold. Sometimes you can’t avoid it, though, so thin t-shirts (I have a collection of vintage style tissue-thin tees like this but cut for women) and tank tops provide another layer under a sweater without being too bulky.
Other than that, not unless I’m wearing a blouse I consider too sheer.
Lady here. I wear a t-shirt or tank underneath my regular clothes in the autumn and winter seasons, pretty much for extra warmth. When it gets warm I just use a bra.
I’m in Minnesota, so I’ll occasionally layer a flannel over a tee, but for the most part, no, I’m not really comfortable with an extra shirt.
I usually wear a colored t-shirt, and if I get cold I put a button-up shirt on over that.
I prefer not to wear an undershirt because I detest being hot. Sometimes it’s necessary, like if the shirt is uncomfortable or a non-breathing type of fabric, or if it’s a thin dress shirt. I only have a couple shirts like that that I wear with any regularity.
Depends on the shirt and the temperature. I have an array of A-shirts and t-shirts (both crew and v-neck) that I wear under other shirts, mainly in the winter. I always wear one under a button-down dress shirt, not matter the season, but rarely under a polo unless it’s really hot and I’ll be outside, where an a-shirt (sorry, hate the “beater” nickname) works well as a sweat barrier and doesn’t really seem to make me any hotter.
This, and it tends to cut down on the wolfman chest hair look as well.
I tend to loaf around the house in just the undershirt though.
(quick question- do wife-beaters really help with the sweat? They look like they don’t really cover up your armpits very well.)
I only wear a T-shirt under a dress shirt in cool weather. Since my dress shirts are all or mostly all cotton, I find them comfortable.

I usually do except when I’m wearing a polo shirt. Polos usually feel fine even when sweaty, but most of my button-down shirts do not.
Male. Always. Usually a T-shirt but sometimes an A-shirt if the outer shirt is already a T-type
Sometimes - Only when its cool weather, I will wear one (usually colored - grey or black) under a button up long sleeved shirt. T-shirt tail is always tucked in even if outer shirt isn’t.
I will wear a colored T-shirt alone in the summer but never as a undershirt.
I can never figure out the reasoning of some of the styles. My teenage sons will wear a white T-shirt under a colored outer T-shirt. Or the thing I see younger guys doing: a white regular collared T-shirt under a V-neck T-shirt or Polo shirt with both shirt tails out and the white tail longer and hanging out from under their outer shirt.
My outer shirt is a t-shirt.
Always - either a t-shirt or a singlet. They keep me warm in winter and soak up the sweat in summer.
The only shirt I wear is a t-shirt. The only time I wear any other kind of shirt is with my tux, maybe once a year . . . without a t-shirt.
Always white T under dress shirts for smell/sweat - I travel for work and get 2 wears out of the dress shirt, less packing.
Occasionally color T or white T under casual shirts for warmth and fashion.
Often color T or logo T alone.
I’m a female but I wear tank tops or camis when needed.
As for my son, I put a white shirt under his button downs (or a white sleeveless Hanes if its really hot). To go without just looks…tacky.
I don’t wear undershirts, but I do wear cotton T shirts under polos and long sleeve shirts.
In this tropical climate, all but the lightest, softest fabrics can feel very uncomfortable once the heat and humidity start having their effect. It adds wear and tear, and thus expense, to sweat up dress shirts. So I am almost always wearing some form of undershirt unless I’m in a t-shirt based outfit to begin with.
Female. Always. I like to have something between my bra and shirt.
