One of life's most insignificant—but nonetheless pesky—challenges is choosing between "hair up" or "hair down." To save you some frustration and time this holiday season, we've devised 21 hairstyles that complement seven different dress necklines, from an off-the-shoulder look to a seriously head-turning plunge.More
Down with natural texture: A Bardot neckline exposes the neck, shoulders, and collarbone, so if you're feeling a bit too bare, just downplay the expanse of skin with insouciant, air-dried waves.
Half-up, half-down: There's no faster way to feel like a princess than pulling up part of your hair and leaving the rest to tumble down your shoulders. Use bobby pins or pretty coordinating accessories.
High pony: If you really want your décolletage to take center stage, pile your hair on top of your head and wrap a few inches around the base to camouflage the elastic. Party ready in no time.
Loose side braid: What's the point of a single strap when you cover the other shoulder? An undone braid allows you to keep the length and the casualness without compromising the silhouette. (Just make sure it's on the same side!)
Retro waves: Finger waves—with the rest pinned up, depending on your length—are totally Old School Glamour.
Down + behind: Yes, you can absolutely wear it down—because your hair is resting on your back, the spotlight remains on your shoulder.
