Size Guide


The Seamless CPH undershirt are available in four sizes, that we believe will fit everyone. The undershirt is made from 96% TENCEL and 4% Elastane, which makes the undershirt highly flexible. This means that even though you are a packing a bit of extra weight you will still be able to fit the XL undershirt – you might even experience that the undershirt keeps everything together very nicely.

As a general rule, you should buy the size you always buy when getting a new t-shirt. The fabric is highly flexible and will therefore fit almost any imaginable body type.

If you are light as a feather, the small size will likely be the best choice for you, even though you would typically go for an XS.

If you are packing a bit of extra weight XL will suit you even though you might use double or triple XL in regular t-shirts. The founder of Seamless CPH is 1,98 cm and would normally wear an XXL t-shirt – for him, the XL is perfect.

The invisibility of the undershirt is possible due to three things: The seamless design, the fit and the colour. The undershirt is available in three colours: 

Bare Oak – choose this colour if your skin tone is light or if you want a colour that better suits your winter pigment. 

Calm Cedar – choose this colour if your skin tone is medium or tanned.

Royal Mahogany –  choose this colour if you have a darker skin tone.
