Thank you for viewing. This is a set of two MIKIHOUSE jumper skirts. They have cute animal embroidery and are recommended for both everyday wear and going out. The sizes are 90 and 100, but the waist sizes are almost the same, with the main difference being the length. Therefore, I think they can be worn at the same time. In our house, we wore them from around 1 year and 3 months old to around 3 years old. There are some stains and fading from use. I think they are not very noticeable at a glance, but this is just my personal opinion, so please check the photos and consider before purchasing. Thank you for your understanding of used items and home storage.
