A thin base layer under a shirt in September and October
Short answer: A thin layer under a shirt in September and October is a long-sleeved T-shirt that sits close without being tight and does not show through the shirt. Choose a light fabric weight, a quiet colour and a length that stays tucked in. Here are tips for the first layer of autumn.
Why a thin layer makes sense now
In September and October the morning can be cold and the afternoon mild, and a thin layer is easy to adjust. Under a shirt, a long-sleeved T-shirt adds a little warmth without needing a thick jumper. If the day turns warm, it is easy to unbutton the shirt or take it off.
Choose a close but not tight fit
The layer should sit near the body so it does not ripple under the shirt, but it must not pull across the shoulders and arms. Lift your arms and bend your elbows, so you can feel whether the sleeves tug. Look at a bamboo long sleeve T-shirt for men and choose a size that suits your body.
Fabric weight and feel on the skin
A thin, soft fabric often feels pleasant against the skin and does not add bulk under the shirt. Viscose from bamboo is smooth and light, which makes it a reasonable choice for a layer that sits close. Avoid very thick fabrics if the shirt is slim, because it quickly becomes tight.
Colour and neckline
Choose a colour that does not show through the shirt fabric and goes with the colour of the shirt. White and light grey can show through a light shirt, so a skin tone or a darker colour is safer under light shirts. The neckline should not show above the collar, and a round neck is usually the most discreet.
Length and tucking in
The layer should be long enough to stay in your trousers when you move and sit down. A T-shirt that works its way out creates a lump around the waist and a cold strip across the lower back. Bend forward and reach up, so you know whether the length holds.
Socks and underpants in the same theme
An autumn layer is not only about the upper body. When the temperature falls, socks can give a soft finish, so take a look at all bamboo socks for men. And choose underpants that do not leave edges under thin trousers, for example bamboo underpants for men.
Washing so the layer keeps its shape
A thin layer is often washed, so it is worth looking after the shape. Wash gently following the care label of your own T-shirt, and avoid high heat in the tumble dryer, which can make viscose shrink. Shake it out after washing so it does not dry in creases.
When it gets colder
When October draws to a close you can build on the layer with a jumper or a jacket on top. The thin layer underneath stays the same, and you change only the outer part according to the weather. Consider several layers you can take on and off instead of one thick one.
Frequently asked questions
Can a long-sleeved T-shirt be worn under a shirt?
Yes, if it sits close without being tight and the fabric is thin enough not to create bulk. Choose a colour that does not show through the shirt.
Should the T-shirt be tucked into the trousers?
It is a good idea, so it does not ride up and leave a cold strip at the lower back. Choose a length that stays down when you move.
Which colour suits under a light shirt?
A skin tone or a light, warm shade shows through the least. Check the colour in front of a window before you wear it out.
