This blouse and ribbon were received as a gift. The previous owner wore them once. The ribbon has elastic and is designed to go around the back of the collar, as shown in the first photo. The blouse is size 165, but my child wore it once. Total wear: twice. ⚠ I selected size 160 because that's the largest size available, but please note that the blouse is size 165. I understood that there would be a difference in our children's builds (my child is shorter), but I was grateful to receive them and let my child wear them. The size was somewhat concealed because my child wore a uniform over the blouse. It was only once, and my child said it was fine since it was a gift, so I was grateful to let them wear it. Thank you. I hope someone will wear them. Thank you. I will take measures to prevent water damage and ship via anonymous delivery.
