I came across the word "musset" in Gregory Maguire's Wicked--
Her green traveling gown with its inset panels of ochre musset suggested wealth, while the black shawl draping just so about the shoulders was a nod to her academic inclinations. (p. 84 in my edition)
Does anyone know what exactly the word refers to? It plainly has something to do with clothing, but what in particular? Is it just an invented word? It's not in the OED, and my Google searches led to naught, but I'm wondering if it might be a recondite technical term for something.
