Elizabeth; The Golden Age

Although Elizabeth the Golden age is set a bit earlier than 1600, a few of the dresses have styles that continued until the end of the Elizbethan era.

I especially like the stand up collars that are prominant in the film, from this screenshot of Bess's costume, it appears to have a wire structure underneath to keep the shape, and presumably the lace has been stiffened to keep the shape aswell.
