Unlike the elusive bobby pin (you've either got a whole pack or you can't even find one, amirite?), the elastic never lets you down. But real talk: Even though you've always got one at the ready, do you *ever* use it for anything other than a messy bun/pony? Add a few more looks to your repertoire from the ones ahead, and never crawl on the floor desperately searching for a tiny piece of bent metal again.
Most of us would arrange it so the loop rests at the nape of the neck, but there's a certain charm to falling-out styles, as seen at Derek Lam. Just make sure your outfit is more apéritif than après-gym—high-low, and all that.
Another loop...with a twist, har har. At Ryan Roche Fall 2017, stylist James Pecis bricoleur-ed a Topsy Tail, but with some care and practice, you could invert your pony without a special tool, then fold the tail onto itself, sticking the ends through the elastic to make a north-south bow.
At Prabal Gurung, hair on each side of the head was twisted, then brought together at the back. Run your hair back to front over the crown for flyways, which, no, are *romantic,* not embarrassing.
Yup, mega pretty wedding hair that only requires one elastic. (If you replaced the pins here with a clear band, that is.)
Trying this on actual wet hair not advised (stretching, breakage, etc.), but on product-dampened tresses à la Skylar Grey at the Grammys? Yes, please. Apply your conditioning treatment of choice, comb through for even distribution/those cool tooth tracks, then make a loop with the ends on top. Fold those over and tuck in for a ripply effect.
BAM. To adapt this epic Masha Ma look for real life, ignore the tiny ponies on the sides and focus on the middle section. Starting from the hairline, twist two sections, incorporating strands from the sides as if you're French-braiding.
Scene-stealing outfit? Holly Fulton's cool, boyish hair is for you. I'd gel just the top half and create a deep side part. (Bundle the rest together with your hair tie.) While the front's still wet, take a comb at the hairline and brush straight up.
For days when you want to wear your hair down but some of it just isn't cooperating, Pucci's just-about-nonexistent pony is the solution. Air-dry, create a laser-straight center part, then put on something shiny.
If by some miracle your elastic already has things dangling from it, you're set. If it doesn't, you could just go without for a sweet throwback look, or do what they did at Marchesa and glue the feathers in with hair glue. Either way, make sure to anchor your tiny hairline pony at the arch of your eyebrow for the most flattering look.
*deepens voice* Chiiiiiiiic. Gather your hair into a low pony, then twist. Next, fold the tail onto itself so the coil doubles, then secure with your trusty hair tie. (Technically, clear would be more Céline, but Phoebe Philo wouldn't worry about it.)
