Where would I find this fabric?

X-Trace: DXC=cmoTMa;I@bL0Y@N202YQOEm4K\QM1CV^@1OYf0H`?;XA0iEAdhEXc] 63% Cotton

I have no idea what it could be, but I have taken clothing with fabrics of unknown type to the fabric store and asked a very knowledgeable employee there (note: not all of them are really knowledgeable) what type of fabric it is, and she usually has been able to tell me.

Maybe if you could find a picture of it in a catalog or post it on a web site somewhere, people could be of more help. What you have could be anything from slinky to Sparkle to whatever.
