This is a Polo Ralph Lauren polo dress. Purchased from Seibu around spring 2023, it has been worn about 5 times indoors. I bought different sizes for my twins. It's a romper design, so it's very convenient to wear just one piece. It also has some stretch, so it can be worn for a while. It's a cute design perfect for summer. I think the size is around 80-90. I'm selling it because my children have outgrown it. Would this suit sisters, or twins? Please contact me if you would like to purchase a single item.
