I have finally scanned the pic of the Princesse de Condé. Here is the link: http://www.houseffg.org/belphoebe/princesse.htm
Notice the doublet. It is the same cut and even the same neck ruff. The difference is in the sleeves. Sure, one is slashed and the other is not. One has an overdress and the other does not. One lady has her hair braided, and the other one is wearing a hat. Other than that, even the buttons look similar. Heh.
