This is a comfortable, soft knit. The navy color is accented with beige. It's a free size, but it feels a bit large on me, and I usually wear a size M, so I think it would fit someone who usually wears a size 11 (Japanese size). Or, you can layer it like in the photo, and it will look cute on a size M person too♪ There is some wear and tear (slight pilling), so please understand before purchasing. For those who like the Baycrews brands such as IENA, spick and span, and relume.
