Query: Stylish, functional, and comfortable!

This is a wonderful headband! It's very flexible and not at all binding, yet easily keeps my hair under control. I especially like the fact that the teeth don't show while you are wearing it! I purchased all of the other headbands Amazon had to offer, and with the exception of this one, the others were uncomfortable. I plan to purchase a few more of these.
