I wear the Robes of Summer on my mage, whenever i use Misty step, or get KOed and need to get helped up or revived i get brought back wearing blue armor when the robes of summer are Red. Unequipping and re-equipping the armor restores its color.
Revived definitely has some bugged animations. I gave Astarion's clothes to Tav (F). Tav was KO'd and her cheeks popped out of the pants. After reviving her cheeks stayed out. I reloaded an old save to undo the bug.
Okay, I've been testing different armor with the revivication bug. And with Tav (F), I've had a multiple body parts pop out. The common factor I'm seeing is unexpected armor for the character.
