Prom dress shopping 101: 1. Look for embellishments! Sequins, textures and lace details all help make a dress feel extra special. 2. Keep the silhouette age-appropriate. Mesh panels (like this gorgeous illusion neckline) are a great way to compromise with teens. 3. Have fun! Prom dresses are one of the few wardrobe opportunities where a brightly colored ball gown is the norm — so go big!
