Here is my submission!
The vanity set would be called "Serene's Set".
I've also included a piece of concept art which I seperated with a black line.
Helmet: Serene's Headgear (Bottom Right of the picture).
A pair of headphones. The left side (seen when facing right) is an altered Light Shard with an Amethyst in the center. (In context, that is.)
-would show the character's full hairstyle
-the gem on the left part would be visible in the dark
-the glasses (top of the picture, on the character artwork) are a part of the set
-possible extra: boomerangs could be replaced with the left part of the headgear
Torso: Serene's Vest and Sweater (bottom center of the picture)
A simple vest and sweater. It also has a scarf.
-vest is blue
-sweater is pink
-the brown is a scarf
-Tooltip: The Scarf was crafted by her best friend, Esther
Pants: Serene's Pants (top of the picture)
There's a hamster in the pocket. Besides the hamster, they're just pants.
-possible extra: when sitting on a chair, the hamster could jump out of the pocket.
The concept art is a fox-boy.
Good luck to everyone else here!
Edit: Sorry if the picture looks a bit choppy, I added some stuff in MS paint, like the hamster.
