This is a Lovetoxic 2-piece set. Both items are size S, which is equivalent to 140cm. They can be worn separately. I purchased this as a 3-piece set, but the long-sleeved top had a stain, so I am only selling the two items. Measurements are approximate due to being taken by a non-professional, so please be aware of potential errors. [Top] Bustier The length can be adjusted in 3 stages with the string in the back. Measured at the middle position, it is approximately 34cm. [Skirt] Length is approximately 38cm. There is a pocket on the left side. It has pants-style lining. It has an adjustable elastic waistband. Please ask if you have any questions.
