Okay, I am in the process of making some Sandman uniforms.

I need some help with the fabrics though!

I know the vest and belt are Polyester Doubleknit, and the gray is just a Knit.

Does anyone know what the shirt and pants are made from?
Judging from the color differences when the light hits it, the shirt doesn't look to be the same fabric as the vest.

Can anyone help? Anyone here have an original uniform?

Thanks! :D
