On the rare occasions I wear my hair down, I usually have a black rubberband wrapped around my wrist just in case I want to put it up. So, when I discovered that a neighbor of mine recently launched a line of chic bracelets that double as hair ties, I took notice. After all, these are no ordinary hair ties; they're Cartier Love bracelet compatible! The rose gold disk, above middle, is my favorite style, and it's $18. Check out the others, featuring green onyx, rose quartz and tourmaline .
