@SirSidneyRuffDiamond , I also ordered this. It arrived today. I ordered a Medium and as a 12 up top this fit perfectly.
About that, this is odd, but it fit nicely, and looked great withthe wool toast trousers from a few years back that are of the same shade and i just happened to be wearing them. It made a really cute outfit, very hamptony, but I'm sending it back. I thought it was thin and although very cute I didn't think it was £95 cute. I also ordered the stone cotton linen twill trousers in my usual toast trouser size and they are too big, I shall keep my eye out though as I liked them a lot. I'd also ordered them inolive but I don't know what I was thinking, this would be hard to work in to my wardrobe.
