See: sack dress, take 1.
I think I tried on six different belts with this dress today. It was a three little bears style dilemma. Some were too wide, some were too casual, none were “just right.” Frustrated, and belts strewn errywhere, I settled on the old “scarf-around-the-waist” move. I checked Pinterest, and Olivia Palermo’s done it, so it must be acceptable.
