Both items are Skinhead items in my book.
They may not be vintage trad skinhead wear 68-72 etc, agreed.
But I like to mix my wardrobe with items I like from all the skinhead era's. Even late 70's revival (Not Oi! tho)
I think it would take great discipline to ONLY wear original late 60's skinhead items these days. Fair play and respect to anybody that does tho.
Depends how you look at it I suppose, and what you want out of it. Check shirts weren't wore at the start of the movement for example.
Was it just plain shirts and vertical stripes at first?
