As others have noted this shirt runs about one size large. However, if you were to launder it as soldier's invariably did (boiling in water and line drying) it will likely shrink. That's not a recommendation that anyone should follow. As to the quality of the shirt it is top notch material and craftsmanship.

It was itchy, so I know it was very very close to the real thing.
