Occasionally we come across a look that doesn't necessarily translate to a traditional prom look, but it's still so good, and, in fact, would be perfect for the girl who's not into a ton of sequins and sparkle. Such is the case with Ashley Madekwe's Lanvin ensemble. It's actually a strapless top and skirt combo, but the rich navy and emerald hues and luxurious fabric give it a definite dressed-up feel. Plus the gold metallic sandals and green minaudiere add a touch of sparkle that elevates the entire look. Ashley finished the look with a smoky eye and pale pink lip, but it would also be gorgeous a shimmery gold shadow and a bold lip. And while she opted to skip the sparkling jewels for The Foundation for Living Beauty's fashion fundraiser, you could certainly dress up this look even further for prom with dazzling drop earrings, a rhinestone statement necklace, or bold gold cuffs.
