Vineyard Vines plaid button down jacket

I have a brand new Vineyard Vines brushed jacket that is a size SMALL. I will say it does run large and is more of a medium or medium to large...very roomy. It is very heavy for those cold days of winter....or an Alaskan trip. Again, this is a heavy material jacket, not like a thin plaid flannel shirt or even close to one. Very well made and not cheap by any means, with trim done in a light denim. Vineyard Vines still sells this jacket on their website for $159.99...same size.
