Sara Jean Underwood may only stand 5-feet-2-inches tall, but she packs a whole lotta sexy into that petite frame. We've taken a look at this former Playmate in GIF form before, but we never realized how much she likes to dressing up in costumes. She can do Black Widow or Yoda or a woman with pizza for nipples (really). Girl is multitalented, as evidenced by her ability to look traffic-stoppingly hot even when fully clothed -- but she's better takes it all off.
