Our suppliers provide these measurements. Note that product dimensions may differ by up to 2 inches (5 cm).

Customers in the US should consider selecting one size larger as the EU sizes from this supplier tend to be smaller compared to US sizing.

A useful tip! Compare the measurements of one of your own items at home with those listed in this guide to ensure the best fit.

A Length

Start the tape at the top of the tee right next to the collar (Highest Point Shoulder) and extend it to the bottom edge of the shirt.

B Width

Begin measuring from the seam right under one sleeve and extend the tape across to the seam under the opposite sleeve.

C Sleeve length

Start the tape at the top of the set-in sleeve and measure down to the sleeve's hem.
