EUC Vintage Upstream XXL light blue jacket.

EUC Vintage Upstream XXL light blue jacket. Looks like silk, feels a bit more coarse. There is no material contents tag or I would definitely post a pic! I purchased this from a thrift store myself and never worn it. Reminds me of the 90s. I have no attempted to wash or clean this at all. Also have not steamed it to get wrinkles out. Please make an offer if interested! :)
