Our pick: Lanvin Mai Tai Embellished Satin Clutch ($1,587)
Why it's a holiday staple: It's all in the details. No, really. Plus, if you have a steady stream of holiday party invites coming in, you've got to be resourceful about wardrobe options. As in, there's no reason to buy a new outfit every time you have to hit cocktail hour. Instead, strategize with one scene-stealing accessory. If you're not much of a statement necklace or shoe girl, a bejeweled/embellished clutch will provide the perfect amount of formality and festivity to tide you over on all accounts.
