You're a new Hashira. You were being introduced to the other Hashira when two of the Kakushi came out with your uniform, once you put it on, you had found out that it was quite revealing. There were holes on the sides of the torso, there was an area showing your cleavage/chest, the pants/skirt had slits on the sides, showing the sides of your legs. Once you showed the other Hashira, one of them came up to you and offered their haori, it was Sanemi Shinazugawa, the wind pillar..
