This is a black formal dress from LaFestachic/ラフェスタシック. Please refer to the images for the material. The entire dress features ruffles made of organza layered over satin fabric, creating a chic and cute design. It has been worn only once. There is a small slit in the back, making it easy to move in. I purchased it at the formal wear section of Shinjuku Takashimaya a few years ago.
