Look familiar? Audrina wore this What Comes Around Goes Around dress in the “Hi Lauren, It’s Spencer…” episode of The Hills when she dropped the news to Lauren at BLVD that she would be attending Speidi’s wedding.

Why are we in love? From its subtle collared halter straps to its liberating open back, this above-the-knee Savoy dress is smart and sexy, sultry and sophisticated wrapped up all into one sensational silhouette! And, to be perfectly honest, we were so inspired by Audrina’s savvy lunchtime look that we can’t wait to pair it with our favorite gold jewelry. Perfection!
