Wright navy overshirt

Chest:
The garment size is to fit the chest measurement as shown. Measure around the fullest part of your chest (the full circumference, keeping the tape well up under your arms and across the shoulder blades).

Waist:
Measure around your waist (over your shirt, not over your trousers) at the position where you normally wear your trousers. Keep the tape a bit loose, so it is comfortable.
