BtSSB Unico Scallop JSK. Comes with waist ties and detachable pin for front of dress. Condition is good, just wrinkled from being in storage.

Lolibrary says max measurements are 98cm for bust and 76cm for waist. Corset lacing in back provides some give, but material is not stretchy.

Was once my dream dress, very sad to see it go ;_;
