An undershirt under a shirt without it showing
Short answer: Undershirts for men worn under a shirt show less when they are thin, close-fitting and in a colour near your skin tone. The neckline must sit below the collar, and the fabric should have no pattern. A white undershirt under a white shirt is rarely the best choice.
Undershirts for men and the colour under the shirt
Undershirts for men that you choose for a light shirt should be close to your skin tone rather than white. A white undershirt can shine through a thin white fabric, while a neutral or light sand shade blends in with the skin. Check the colour in daylight before you decide.
Thickness and fabric
A thin undershirt shows less than a thick one, because it does not form a clear edge. The fabric should not have ribbing or a pattern that can be seen through the shirt. Bamboo in clothing is viscose made from bamboo, and the fabric is often soft and light, but thickness decides whether it shows.
The main choice under shirts
If you wear an undershirt under a shirt every day, take a look at the range of bamboo undershirt for men. There you find models with different necklines and lengths, and you can choose the one that suits the shirts you own best.
The neckline
If the undershirt is round at the neck and the shirt is open at the collar, the edge can peek out. Choose a deeper neckline if you wear the shirt with an open collar. If you button the shirt up to the neck, a round neckline is the most discreet, because it sits under the collar.
Fit and length
The undershirt should fit closely enough not to fold under the shirt, but without pulling. It must be long enough to stay tucked in when you sit and move. An undershirt that is too short comes out of the trousers and gathers at the stomach.
Watch the seams and sleeves
Seams and sleeve edges can show through a thin fabric. Choose an undershirt with flat seams and a soft edge around the sleeves. If you are unsure, try it under the shirt in front of the mirror and look at the back, where a visible edge is often overlooked.
When you want more than an undershirt
If you use the undershirt as a first layer in the cold months, a thin extra layer under the shirt can keep you warm. You can also look at bamboo sleepwear for men if you want to gather your day and night clothes in the same fabric type. That makes the laundry easier too.
Washing and storage
Wash the undershirt according to the care label and use a moderate temperature. Dry it on a line so it keeps its shape and does not shrink. Use several undershirts so you can change every day. See also bamboo T-shirts for men if you wear them together with the shirt.
Frequently asked questions
Which colour shows least under a white shirt?
A colour close to your skin tone shows less than white, because white can shine through a thin white fabric. Check in daylight.
Round or deep neckline under a shirt?
It depends on the collar. If the shirt is buttoned to the top, a round neckline works well. If the collar is open, choose a deeper neckline so the edge does not peek out.
Can a thin undershirt still give warmth?
It gives an extra layer, but not as much as a thicker one. If you feel cold easily, choose a slightly heavier quality that still lies flat.
