Next LevelApparel Men's Triblend Knit Crewneck T-Shirt, Vintage Blk, Large

Is the vintage white see thru?

Vintage white, Heather white and white all look exactly the same in their pictures. Can someone please explain the difference between them?

Which fabric blend is this made from? 100% Polyester 50% polyester/25% combed ring-spun cotton/25% rayon jersey? It can’t be both. :)

Is vintage Royal just a heathered Royal or does it have black thread mixed in with the blue thread?
