SIZING GUIDE
To get the most reliable fit it's recommended to measure the pit-to-pit width of a similar garment that fits you well.
Here's how to do it:
-
Lay the garment flat: Smooth out any wrinkles for accuracy.
-
Measure from armpit to armpit: Take a measuring tape and measure across the widest point between the two armpits.
Remember, your actual chest measurement (taken around your torso) may not be accurate for choosing clothing sizes. For example, if your chest measures 42" around, dividing that in half gives 21". But a shirt with a 21" pit-to-pit width would likely feel too tight because garments typically need an extra 1-2 inches for comfortable movement.
Please note that the below tables are a guide and clothes by their very nature will always be slightly different, garment to garment. There is a tolerance of up to 2cm on the measurements below.
