Anyone have information on temporary lip sewing?

My wife, daughter and I will be attending a full scale Halloween costume party as a Day of the Dead family. My wife has made all the costumes and will do the make up. As a topper to the costumes we all are going to get our lips temporary sewn together. She has a reference for a piercer that will do it safely with surgical equipment. It will be an X suture in the center and two single stitches on each side. Our appointment is for noon (well before party) and we were told if we take Tylenol the pain will be subsided by evening.
