Set of a 140 black tight dress and a ribbon dress. Worn once for a piano recital ^_^ There's a slit only on the lower left side, so it doesn't seem like it would be difficult to walk in. The ribbon is removable. The length can be adjusted with the straps. I think it can be used for formal occasions ^_^ Height 140-145 cm, slender build, I've also included a photo of it being worn, so please use it as a reference.
