Two 1/4" strands are braided together for a beautiful, Grecian-inspired band that's best when worn close to the hairline. * To measure your head: Use a cloth tape measure or a piece of ribbon or string. Wrap it around your head at the point where you will wear the band. It should feel neither loose nor tight. If using ribbon/string, measure the length against a ruler. Small/Medium Hairbands Fit 19-1/2" to 22" heads Medium/Large: 22" to 24"
