The band is about 1 1/2" wide and the center top goes up 4 1/2 inches above that (6 inches total). The crown ships flat so you can fit it to your head. Just glue or staple the back to hold it together. The one in the picture is just held with a hairpin.
I also have the Princess Bubblegum costume available in women's, chlidren's and plus sizes available in my shop!
Please convo me if you have any questions.
I am in the US and make all my items myself by hand. This is my full time job, so you can be assured when I work on your costume, it receives 100% of my attention and I'm able to spend the time on it that it needs. You don't have to worry I'm trying to work on costumes after a full day at an outside job or trying to rush to get it finished. My customers are always welcome to convo me at any time and I try to answer all convos as quickly as I can, most within a couple of hours (unless it's the middle of the night).
