Dorothy Perkins Vintage Blazer Size 12

This is a long navy blue blazer from Dorothy Perkins in size UK 12.  The blazer has long sleeves and wide lapels and is double breasted with gold classic buttons.  It is fully lined and is a polyester viscose mix fabric.  In excellent vintage condition, but there is a very minor mark on the front which I have shown in the photos.  Please see photos for measurements and please note it does come up slightly smaller than a standard UK size 12 today.
