OK, here are the pictures I took of the same gown. Despite some differences in the color, it's all the same gown. The gown color is navy with black velvet trim and gold piping. The hood will be provided for me, but I need to accommodate it when I sew the gown.
the sleeve has not real cuff, but instead is sewn into the lining, kind of like a bubble skirt.
They have run a length of elastic, sewn only on the top edge, along the hem, which I think is a pretty ingenious idea. It stabilizes the hem without compromising the "bounce" of the crepe (even poly crepe has bounce).
There are many more pictures, but the siren song of the dissertation calls me back. More pictures to come.
