I think the best size for people who usually wear 26-27.5 is the best fit. I've worn them a few times. There are no stains on the surface. They are not currently sold, and there are no plans to re-release them, so they are quite rare. The number of sales is also low on other sites, so I don't plan to hold them. In Tokyo, I see colors like green, but I've never seen this pink one. They look really cute with denim, so I recommend them! If you have any questions, please leave a comment.
