Sorry! I'm not sure how my comment ended up where it did...hmmm....maybe the Zombies are still attacking?

Anyways, If you turn to page 177 in Kohler's History of Costume (cause I know you have or can just borrow it), there is a 14th c chemise that is nothing more than spagetti straps. My guess is that is what she is wearing underneath. The chemise has a very wide neckline which explains why you can't see it underneath the gown.
