The size chart
Measurements in inches
“Fits chest” is your body measurement. The collar label shows the size printed on every MUAMS neck label — for example Medium : 38 cm.
How to measure
Grab a tape. Two minutes.
Wear a thin t-shirt, stand relaxed, and keep the tape snug — not tight. Tap a measurement to see it on the shirt.
