For the movie Marie Antoinette (2006), the concept was to keep the colours very light and fresh, almost candy like, for the younger generation of the Dauphin and Dauphine, and to reserve deep saturated colours for the older characters of King Louis XV's era.
The Comtesse de Noailles belonging to the latter group, she gets to wear this gorgeous deep teal blue, long sleeved, compère front Caraco jacket with gold lace accent paired with a pearl grey skirt.
Of course, she also wears a matching hat!
Luckily enough, teal blue satin is fairly easy to find (as opposed to a specific brocade for instance). Besides, I know that colour would look beautiful on me.
Sigh! I really have too many projects for just one lifetime!
