I noticed when looking at the RN website that there is now a rig for ratings with a short sleeve white collared shirt instead of the traditional white front worn with jumpers. I'm wondering when this came into being? When the RCN wore traditional seaman's uniforms, the white front was usually referred to as a "gunshirt" and the rig with bell bottoms and gunshirts minus jumpers was known as 2A. Since our previous dress regs were derived from the RN, was that the designation in the RN also? I'm also wondering if the RN ever wore gunshirts with a vertical crease down the centre? Just curious.
