Worn only once. Then dry cleaned. From the official website: This is an occasion dress set featuring a bottle neck short top and a mermaid line dress for a beautiful silhouette. It's an excellent set that can be worn together or separately. The short bolero uses three-dimensional lace and features pintuck design, paying attention to the back style as well. The camisole dress, with its mermaid line hem, sways beautifully with every step, and has a sleek, flowing silhouette, creating a simple yet impactful dress. The shoulder straps can be adjusted by tying them. By not using adjusters, the straps won't bunch up under the bolero, and the camisole dress can be worn neatly on its own.
