Courtly attire

Exploration Stage: Cards of Fate
From: Mei
Description: It's got a big collar ornament. It's a beautiful thing, but it's not used all over the empire. It was only popular in my father's time. It was made shortly before the war with Suzaku. Father would be pleased if you put it on. Can you find it for me?
Completed: This "large collared ornament" will add dignity to our traditional attire. Our father, we are almost ready to present you to the emperor. We just need a few more things.
