Worn once indoors. The blouse was not originally included, and only the JSK is for sale. I believe it was probably an S size, but my memory is vague, so I apologize. The back part is made of elastic and is stretchy. When I, who am 152cm tall, wear it, the length comes to around below the knee. Approximate size details: Bust: 76cm, Length: 92cm There are long ribbons on both sides of the waist, and one on the chest as well. Both are sewn on and cannot be attached or detached. The shoulder straps can be adjusted in two stages. I checked it once and determined there were no issues, but I apologize if I missed anything. Please refrain from purchasing if you are sensitive to this, as it is amateur-managed.
