The princess of Kinmoku who escaped to earth when Sailor Galaxia attacked, Princess Kakyuu is said to smell of sweet osmanthus, which is the recurring motif of her design. There are different versions with regards to her storyline in the anime and manga, but she is similar to Sailor Moon as she also has her own senshi, the Sailor Starlights.
The cosplayer looks like a doll in this photo. I’m guessing proper make-up and lighting gave that effect. Beautiful work!
