Vintage Brooks Brothers Shetland Wool Sweater Oatmeal Gray Size Large. The Shetland Wool Sweater is no longer manufactured by Brooks Brothers. See sizing pics, I typically wear a medium/large and this sweater has a tighter fit. Possibly was shrunken before it came into my possession. Item is in very good condition, no noticeable pulling or pilling of the wool. Only flaw is that one corner of the Brooks Brothers tag has come off, but would be easily restitched.
