Thank you for viewing. Free size (Worn by someone who usually wears Uniqlo T-shirts in size S-M) This is a pants-style one-piece dress. The back has a slightly open design. It has pockets. There are some areas with slight pilling. Please check photos 4 and 5. If you have any questions, please feel free to comment, and I can add more photos if needed. When shipping, I will try to make it as compact as possible, so there may be some creases. Please understand. Please purchase with the understanding that this is a used item.
