Diary of a Costumer

Okay, so honestly, the more I look at it, the more I think she's holding a really fancy mantle or cloak, not her train. I don't see anything to suggest that it's attached to the waist at all - yes it's hiding most of the waist, but I'd expect to see at least a bit of something on the far right (her left). It has to be an overskirt if it is a train, but there's no sort of facing or balayeuse, which I would expect on something that was designed to drag on the ground. She's also holding her gloves, which suggests to me that the bundle is outerwear. Plus, those pleats(?) on the underside perhaps were meant to be seen in the turnback of an overgarment.
