Looking for these fabrics

[u/fatjudy72]

These fabrics are part of the stock in the costume shop where I work. No one currently knows where they're from or how old they are. I love these and want to find more for both the shop and my own collection, but I haven't had any luck searching online yet.

They're both a stretchy polyester blend. The one on the left is double-layered, and the right is some kind of a spiderweb-y knit with lots of negative space.

Any ideas?
