This is a formal ivory dress from the Renown brand, Restera. The original price was around 20,000 to 30,000 yen. Size 40 is likely a Japanese L size. Roughly, the shoulder width is 37cm, the chest width is 43cm, and the length from the shoulder is about 96cm. It's a rather slim fit, with intricate tucks that create a very beautiful silhouette. Honestly, it's a dress that makes you look beautiful just by wearing it (seriously). After being worn a few times for a short period, it has been cleaned and stored. The tag will be removed before shipping.
