It was mostly dead orbit shaders and the dreaming city helmet and legs, but tomorrow I can tell you the exact shaders I used and the rest of the armor I used.
Here's the load out:
Helmet: Reverie Dawn Casque, from the Dreaming City. Shader Metro Shift
Gauntlets: Lost Pacific Grip, from the vendor on Titan. Shader Vintage Timber
Chest: Vest of the Great Hunt, from the Raid Last Wish. Shader Dead Orbit's Fate
Leg: Reverie Dawn Strides, from the Dreaming City. Shader Dead Orbit's Fate
Cloak: Woven Firesmith Cape, from the Forge Ignitions. Shader Vintage Timber
I tried to find a cape without hood but I didn't have any, so I just used this one because of the effect it cause, it seams it has ears at the top like the cats.
About the rest, I had to try different shaders because they appear different in every piece of armor, and the gauntlets I wanted to use the white rarity because they are the simplest but we can't apply shaders on them.
And about the helmet? This was all about that helmet, I wish I could had a shader like that without the blue part to apply to the rest of the armor, but I had to work with what I have, but in the end it looked cool, and that's what matters.
Edit: I almost forgot, a quick bonus, the emote I used was Beguiling Dance. Doesn't have anything to do with the theme, but I catched a second of it in that position, so it worked.
