Thank you for your answer. The sentence is from the catalogue of a fashion house. It refers to their last collection of scarves and stoles. I wonder if it might be an error for "Shawl"... It is associated with a picture of a stole, though.I've never heard of it; it's not in the OED; and a search for "silk shelley" in Google Books doesn't produce any relevant examples. Together, that suggests it's an error, rather than a rare word. But I can't think of a word similar to 'shelley' that would make sense there. Can you give us more detail of where this picture comes from (what period, what the original language might have been, etc.)?
