String, Felt, Thread: The Hierarchy of Art and Craft in American Art by Elissa Auther spells out the bias of the art establishment. She explains how an artist who started as a sculptor and transitioned to textiles will be perceived as more artistically valid than someone who evolved from quilting to textile art. It's the sort of book I can't read at bedtime because I will not be able to sleep, just lie there seething.
After reading it, I sewed it. If you haven't read it, please consider this piece a wearable book report. It is a textile argument, constructed on top of an old tuxedo: a formal argument, both in logic and dress.
Maybe because I had recently seen a show at the Metropolitan Museum on ceremonial clothing, I knew this had to be a garment. I googled 'ceremonial garments' and that got me started (I found a great image of Prince Charles, which explained what all his badges and medals represented).
