Wilfred Equis Jacket Heathers Grey

The fabric is made in Italy and is amazing quality. This blazer is in excellent condition and has been worn and dry cleaned ONLY once. Even the pockets have not been unsown yet. I'm not sure what the size is as it is not mentioned anywhere on the jacket. I am usually a size 4 or S/M upper body and it fits me perfectly. It's written "ten" but I'm pretty sure that's not the size.
