Thank you for viewing. This is a M size swimsuit for practice at Itoman Swimming School. I am selling it because I outgrew it. I quit the school shortly after purchasing it, so it's in good condition, having been used only a few times. I have a dog. While storage and packing are done in a separate room, there is a rare chance that pet hair may get in. Please refrain from purchasing if you have allergies or are sensitive to pet hair.
