This is standard for most Fashion Shows. Most models are not standard size and the dress must fit to perfection. So, tape, pins, glue,q whatever it takes to get them in the dress and looking elegant as they go down the runway. I was in one where I wore a dress open in the back down below my c----. They used double sided tape to shorten it and make sure it didn't move as I walked. Boy, did that ever itch. I had a mild reaction to the tape. Lol. Some of the girls had pins that would stick them every step they took. Hard way to make a living. Took years to get my complexion cleared up from all of the makeup they put on me.
