This is an authentic, brand new with tags dress by Jovani in a size 0. Jovani recommends a size 0 for a 33" bust, 25" waist and 37" hips. Based on how the dress fit the girl modeling it I believe it is running a little bit roomy so if in doubt you might want to size down. Please measure carefully. Due to the nature of this business we do not accept returns. Note that the sizing and measurements are U.S. This dress retails for $525!
