PENDLETONMen's Big & Tall Long Sleeve Board Shirt Button, Blue Original Surf Plaid

Are these shirts still satin lined, like i reme from the 70's?

I want to wear this as more of a light jacket. I’m not big but buy jackets in XL. There is a 40 dollar difference in price in the XXL and XL. Too big?

Im 5'8" 150lbs will a medium tall be too long? Or go with regular medium?

I just got my shirt. A nice thing but rather on the large side. Can I wash and expect it to shrink a little?
