It’s the hair accessory you know and love and...thought you left behind when you were old enough to register to vote. Fortunately, butterfly clips spring eternal, so you might as well dust off the ones you set to pasture. Use them to cinch half-braided cornrows or, make a middle or side part and use a clip or two to gather some hair to one side. Substitute with a grown-up barrette (or two), like these minimal ones from Valet, or these jewel ones from Neophyte if that’s more your style. Or choose neither and go with a claw clip. Unfortunately Glossier's instantly sold out, but Valet makes some pretty marbleized ones, too. And if you find yourself hot and sweaty, twist all of your hair into a quasi-chignon, and secure it with a claw clip all the same.

What makes a hair accessory an evening hair accessory? Just add something sparkly. Or black. A faux leather headband on top of a slicked-back chignon will do the trick. Go the pony route with a low one anchored with a crystal barrette on the side, or two high ones—one right on top of the other—so that from behind the two ponies look like one long and full one. Use a banana clip to balance all that volume. Alternatively, throw on a headband that crystalizes the meaning of “jewelry for your hair.” Wear it in the traditional sense, an inch or so behind your hairline, or pull it down across your forehead if you happen to stand at the aesthetic intersection of glam and bohemian.

The best thing about the new accessories popping up everywhere is the variety. There are the super skinny headbands (see: exhibit A), satin ribbon headbands (exhibit B), knotted leather ones (look to Lele Sadoughi), pearl encrusted, velvet, and padded options, dainty gold ones shaped like flowers (OK, this one is actually a vintage find), and dainty gold pins in the shape of concentric circles (Lelet NY). Whichever one calls your name, just make sure to leave some hair out front—baby hairs, bangs, whatever you’ve got to work with—to really pull off the look. Or, you can always throw it up in two buns with a pair of Donni scrunchies, and call it a day.
