Or maybe you’re here to break the rules, pairing a daring neckline with a thigh-high slit and statement heels that say, “I came to slay.” Don’t be afraid to play with textures—think sleek satins, luxe velvets, or dreamy mesh overlays—and add a little sparkle with rhinestones or sequins that shimmer with every move. If you’re shopping for yourself, this is your chance to go all out and pick the dress that makes you feel like the baddest version of yourself. And if you’re on the hunt for a gift, a plunging neckline prom dress is the ultimate way to hype up your BFF, your sis, or anyone who deserves to feel like a star on their big night. The best part?
