Season 7, Episode 5
Now, I know this dress isn't metallic, but the dark-gray-on-light-gray embroidery kind of gives it that effect, no? The cape is the same as the previous episode, but the color really pops (well, as much as mauve can "pop") now that Dany is standing outside rather than in her
dark cave throne room. She's also got some sweet lace-up sleeves, perfect for hiding dragon snacks in.
