After researching, this seems to be a WWII era sailor suit. A family member sent it to me.
It's made of wool. Small men's size. There is a name written in the pants. Might be cool to see if he or his family can be located!?
I don't have a use for it, but if you'd like to purchase, pm me an offer. I have an idea of what they are selling for. There is some lint on it (pictured on pants).
