Denim & Supply was a high end denim line by Ralph Lauren and was shuttered in 2018. Band jackets from this collection are highly sought after. They’re not making any more of them. It’s too small for me or is never part with it. Jacket is marked large and runs small. It’s in EUC, navy blue twill fabric, gold eagle embossed buttons, fitted cut, hits approx high hip bone. Made of 100% cotton with gold polyester braided trim. Says can be machine washed, I probably would check with a dry cleaner to see if that’s a better method.
