The Cosmic "Double Infinity" Headband is a turban-style fixed wrap headband with one side Cosmic galaxy themed fabric interlocking with a solid Royal Purple Kona Cotton fabric connected to a comfortable, covered elasticized band at the nape of the neck. The fabric is 100% cotton.
For sizing. it is best to measure the total circumference of your head in inches where the headband would wrap around the head for the most custom fit - this measurement is your size. If you are between sizes, I recommend sizing down as the pattern allows for some stretch. Check out the matching Cosmic mask in the cloth face mask section and the coordinating Cosmic Scrunchie.
