Size 11 I wore this for two seasons during the actual exam period. I sweated profusely during the interview, so I carefully hand-washed it at home. There's some rubbing under the arms. I wonder how much I flapped my arms... Of course, I passed my first-choice school, so I think it's good luck. Haha. For those who are going to take the entrance exams. It gets suddenly cold around November when the exams are held, and the waiting gymnasium will be freezing, so please get through it with wool. Gran Yamaki
