Men's Stylish Denim Jacket size Large must see

This is a Stylish DeNim Jacket in great condition gently used. I purchased this because it was supposedly a XL but it's to tight so I say it's a large. there is no size tag inside this denim Jacket. It has pockets at top and bottom and buttons down the front. I am trying to get some money back that I paid for this on a supposedly reputable selling platform... The hardwear does not match the tag so i consider this a Dupe.... Thanks for looking and Please see my other listings. Thanks
