Prom Spot - Prom Dress Neckline Know-How

You've found the perfect dress, and whether you're baring your shoulders with a strapless style or showing off your (ahem) assets with a daring V-neckline, the right jewelry can make your prom look complete.

Strapless
A choker is always safe because it means your gorgeous necklace won't get hidden under the neckline of your dress. Think basic pearls are boring? Go all-out glam with a crystal-studded style. Keep it classy by pairing your over-the-top necklace with a set of studs.

V-Neckline
A V-neckline is perfect for a pendent charm (plus, it gives the eye a nice focal point). Just avoid longer strands that match the shape of your neckline, which will definitely be distracting. Don a pair of drop earrings to complete your look.

Scoop Neck
Like strapless styles, scoop necklines are ideal for highlighting a stunning necklace. A strand of gems and some glittery hoops will create lots of shine but won't look too busy -- or too simple.

Halter
Your best bet is a princess-length necklace, which should fall just below the throat. Keep it simple so your neckline doesn't look cluttered and add some sparkle with a pair of incredible earrings.

One-Shoulder
This silhouette is already trendy, so you'll definitely need some equally modern neckwear. An opera-length (or super-long) necklace is the perfect choice. Let it hang loose for maximum style. Simple earrings will balance out your dramatic necklace and daring dress.
