It's cute but calm, and has a great autumn vibe. It goes well with blouses now, and with knitwear when it gets cold, so I think it's easy to mix and match.
I fell in love with the design at first sight and bought the IVORY×PU. I'm 156cm tall and it's below the knee. The purple color is deep, so it's not too cute and I recommend it for adults too. I'm a normal build, but there's a little room in the waist, so I'd like to wear it tucked into a knit in the winter.
