This is a three-piece women's suit! It includes a dress, and two jackets, one white and one navy! The size is 9. The skirt length is knee-length for someone 158cm tall! My daughter wore it twice for her graduation and entrance ceremonies, and it has been stored at home since then, but I am selling it because I bought a new one! It has been worn very few times and has been cleaned and stored, so I think it is in good condition! There is a slight mark left from attaching a corsage to the white jacket (photo 5). The pockets on the navy jacket are decorative and cannot be used! I think it can still be used, but please understand that it is a used item!
