Charles River ApparelMen's Classic Rugby Shirt

In the product description the Charles River rugby shirt is described as 100% cotton and also as 77% cotton (23% polyester). Which is correct?

is it actually striped because one of the reviews shows only 3 stripes black on top grey in middle and black bottom

Where are these rugby shirts made?

I ordered a size small and it's too big (fits more like a men's medium). Will this shrink in the dryer to fit more true to a size small?
