I would hang onto them.
I just gave my DS dad's one and only Stetson hat he bought when he was 50, our neighbor got his old coveralls because he is the same size as my dad was and I can no longer wear them, and my DD kept her grandpas good jacket because she was not given the only thing she wanted which was his coffe cup. I still have the only swimming trunks I ever saw my dad in and a,m trying to figure out how to incorporate them into a quilt. They have sharks on them. Sure wish I had some of his shirts to make a quilt. Dad would have been 93 yesterday. He's been gone 5 1/2 years.
