Why Wear an Undershirt?
Many men wonder whether wearing an undershirt beneath a shirt is really necessary. In everyday business wear, however, an undershirt can serve several important purposes – improving comfort and appearance while helping to protect your clothing.
ALBERT KREUZ specialises in underwear for business clothing and in undershirts designed to remain as invisible as possible beneath shirts.
Short answer
An undershirt is worn to absorb perspiration, protect the shirt, improve comfort and support a neat, professional appearance. The key is choosing an undershirt that fits well and remains as discreet as possible beneath the shirt.
The main reasons to wear an undershirt
1. Protection against sweat marks
An undershirt absorbs moisture directly from the skin before it reaches the shirt. This can significantly reduce visible sweat marks.

2. Protecting your shirt
An undershirt helps protect your shirt from perspiration, deodorant marks and odours. This can keep the shirt fresh for longer and reduce how often it needs to be washed.
3. Greater comfort
Undershirts are generally made from softer materials than dress shirts and are worn directly against the skin. This can improve comfort and help reduce friction or skin irritation.
4. A neater appearance
A well-fitting undershirt creates a smoother layer beneath the shirt and can improve the overall fit. The result is a cleaner, more professional appearance.
5. Temperature regulation
An undershirt can provide warmth while also helping to regulate moisture and body temperature. It creates an additional layer between the skin and the shirt.
When is an undershirt particularly useful?
- for everyday business wear with a dress shirt
- during meetings, presentations or business trips
- in warm temperatures
- when you want to reduce visible sweat marks
- with sensitive skin or rougher shirt fabrics
When can you wear a shirt without an undershirt?
An undershirt is not always essential. In extremely hot conditions or under particularly heavy fabrics, you may prefer to go without one. The right choice ultimately depends on your personal comfort and the situation.
What should you look for?
- a close-fitting cut without creasing
- the right neckline – crew neck, V-neck or extra-deep V-neck
- smooth, lightweight materials
- edges and seams that are as flat as possible
- a discreet colour beneath light-coloured shirts

Keeping an undershirt invisible in business wear
In a business setting, it is particularly important that the undershirt does not show. Styles with seamless Clean Cut edges are especially discreet beneath clothing.
