Whether it's a hot date, exclusive party or gala fundraiser, a head-turning dress is a fail-safe investment. All you need is one stand out detail to take an otherwise classic dress to a whole new level. Think oversized bows/flowers, excessive frills, sequins galore and voluminous shapes. Anything goes. Just be sure to pick a dress that flatters your shape. A-line dresses that cinch at the waist suit everyone.
