Vintage Blue & white vertical stripe mock neck rugby shirt

Vintage blue & white stripe rugby shirt from "Britches Great Outdoors" heavy weight cotton, size medium, though I think it's more like a large worn loosely Pit to pit is 24 shoulder seam to bottom is 28" very slight fading of the navy blue color, to be expected with 100% cotton I'm listing this under long sleeve tee shirt, not sure for sure if this is genuine rugby style Please remember vintage will always come with some slight imperfections, though I see only the slight fading I mentioned
