This is a navy blue summer dress from Happy Clover. The size is listed as 1, which I believe is a size 9 (Japanese size). I purchased it for 23,001 yen. I bought it from their website a year ago and wore it about 5 times during the summer for school information sessions and open houses. It has been dry cleaned. The high-quality, flowing fabric is wrinkle-resistant and was very useful in the summer. It was perfect for entrance exam occasions. Please check the official website for the exact measurements. Please consider this item as used. Please be aware of potential folding wrinkles during shipping. Summer in navy is tough, but I sincerely wish you the best in your busy days ahead.
