12 Head-Turning Birthday Dresses, Whether You Love Thigh-High Slits or Cutouts

Victor Glemaud Single Shoulder Dress ($84, originally $335)

An off-the-shoulder style like this dress will tell everyone just who the lady of the hour is. It's understated yet elegant, plus the neutral leopard print makes it easy to pair with the jewelry and shoes you already own. Enhance the neckline with a chain necklace, or go bare to keep the one-shoulder neckline as the main focus.
