It's a one piece, intended to print for a cosplay of the characther from the Super Mario franchise Rosalina that I made and tested. Low-poly version, recomend for smaller sizes, and it's not in the actual size it need to be scale for what you need. It has two small holes so you can place pins or a headband depending on the size you prefer.
If you have any of problems or questions, please feel free to contact me I'll be happy to help you out
