For formal events, nothing adds more polish than a sleek and structured clutch. This black version from Zara looks more expensive than it is, with its faux-leather body and gleaming gold-trimmed edges. Wear it with your favorite LBD to keep your look monochromatic, or take advantage of the sporty green and blue stripes and pair the accessory with like-minded colors. Either way, it's wedding season, so you'll probably need somewhere to stash your lipstick.
