OASIS navy and white school swimsuit with straps, perfect for swimming with a comfortable fit. - Brand: OASIS - Colors: Navy/White/Red - Type: School Swimsuit - Design: With straps - Size: Unknown (as indicated on the tag) Thank you for viewing. I have selected size 140, but it is equivalent to S. S is the size after 140, so it's slightly larger than 140. This is a used item I purchased on Mercari, but since OASIS has changed to Renaissance and no one is wearing this swimsuit, my child doesn't want to wear it, so I am selling it. It is still in good condition and I think it can be worn for a long time. However, please understand that this is a used item before purchasing.
