I've used this dress twice to accompany on the piano, but it was too big for me as I'm just under 155cm tall. I think it would be better suited for someone around 165cm tall. For someone of that height, it would probably be knee-length. Purchased at an H&M store for around 7000 yen. A simple and elegant black dress, perfect for formal occasions. - Brand: H&M - Color: Black - Style: Dress - Size: M Thank you for looking.
