Hair cuffs are really in right now. I have three. From left to right : a gold one from Glitter, a silver from H&M - in stores right now (you can also get them in gold) and a gold hair-cuff from H&M. I actually like the two first the most as they are easier to use and more versatile. The last round gold one can only be used around a ponytail. I use the two others when I do a bun. I always wear my hair in a bun.
