I looked at almost every mod posted in the entire Emporium, I don't recall seeing it, but it would be great if someone could find it.
What I noticed similar was this neck scarf made for Pyro:
Edit: I looked myself and I think this is what you were talking about, "Conagher's Kerchief" by Kebab at Emporium XXV
And here's another one : "The Worker's Rag" by Sexy Robot Void at Emporium XL
I liked the one made by Kebab, that would look good if they were in the game and paintable.
