There’s nothing worse than wearing an undershirt that comes untucked all the time. Not only tall men are facing this problem. You find the perfect dress shirt and it fits ideally. But the undershirt beneath it isn’t long enough and drives you crazy. So how do you get the right undershirts for tall men? And how do you keep your shirts tucked in?

Why wear an undershirt?

If you are not already an undershirt fan, you may ask why you would wear one. There are some clear benefits to the garment that may be a little surprising. In the winter, obviously, an extra layer helps keep you warm. But when it is warm, does this mean that it is no longer needed? Not so, as when the sun is up, the undershirt absorbs sweat. This reduces the chance you get unsightly sweat marks and yellow stains on your dress shirt. If you have chosen a light shirt, the undershirt can serve another purpose. It can stop a sheer shirt being too see-through for formal occasions. In some parts of the world, the undershirt is often worn as a top in its own right!

  • prevents see-trough

Undershirts for tall men

When you are taller than average, a normal undershirt isn’t going to work. It will be the first thing that comes untucked. It will also be uncomfortable and spoil your look. One solution many guys go for is the bigger size. But unfortunately, bigger doesn’t mean longer. It will simply mean you end up with an ugly roll of material around your waist. This will look worse than an untucked undershirt and feel even more uncomfortable.

There are three general categories of shirts, undershirts and t-shirts used by most manufacturers. Standard fit is more about the shape than the size. It features straight sides from the armpits to the waist and is designed for the ‘average’ frame. Slim fitting undershirts have a narrow fit through the body. This means they are tighter than standard fit. A tall slim fit will have greater length as well as a slender fit. Big and tall undershirts are aimed at someone who is both tall and bigger than ‘average’. They have a greater length and are a fuller cut. So when you are tall, getting the right undershirt depends on whether you are tall or big and tall.

3 categories fits of undershirts:

  • straight fit (straight sides from armpit to the waist)
  • slim fit (narrow fit through the body)
  • tall slim fit (greater lenght as well as a slender fit)

Undershirt styles

Once you understand what category of size you fall into, next up is the style. The cotton tank top is the minimalist style. It features a deep scoop neck so it hides under the shirt. This is a design that is wholly under the clothes. They are primarily designed to add a layer for warmth as the bigger armholes don’t collect much sweat.

The most common style is the T-shirt style. Watch the neck if it is to wear under a dress shirt as some can be crew neck style. These are higher than scoop neck and may peek over your shirt if unbuttoned.

V-neck or scoop neck t-shirt style undershirts are the best for under dress shirts. They absorb the sweat and act as insulation. They are also invisible when worn under a dress shirt with the button undone.

So what style works best for what you need it for?
