Does this look like a Beaubrun Brothers work? It is too - also by Charles.

Anne is plainly dressed in this Beaubrun portrait that shows her wearing a skirt with alternating thin columns of gray (or silver) and white extending up from hem to not only her bodice, but also around both sides of her basque waisted bodice. Her dress is as wide as the sayas in contemporary Spanish portraits.
