This is a set-up item, a dress and jacket. I purchased it used and wore it once for my child's elementary school entrance ceremony. Both the dress and jacket have linings and are beautifully sewn. Regarding the size, both the dress and jacket are 120cm (as indicated in photos 5, 8, and 9). As this is a used item, please refrain from purchasing if you are sensitive to imperfections or are seeking a perfect item. Thank you. 100% Polyester
