1705 Suzanne Henriette of Lorraine as Duchess of Mantua by Hyacinthe Rigaud (location unknown to gogm)
The original Wikimedia image appears to be over-exposed so I darkened it and made it "warmer" and adjusted color.
Rigaud portrays the Duchess wearing 1600s-style portrait casual with a split bodice, opened (slashed) sleeves, and a lace-trimmed chemise providing modesty piece and engageantes.
