Maria of Austria wears an interesting gray dress in this 1635 portrait by Frans Luycx. Her Wikipedia article is here.
The German language Wikipedia article about Frans Luycx is here.
She is wearing a saya with the high enclosing neckline and ruff replaced by a lace collar. The conical farthingale has been replaced by some bouffant arrangement, presumably using hoops, that was a preview of 1700s dress. The hanging sleeves are reduced to vestiges while the false sleeves are made of matching material instead of different material.
