This is a set-up from Lowrys Farm, featuring a jacket with a sailor collar and matching tapered pants. The sizes are 110-120cm for the top and 120-130cm for the bottoms. It was worn once for a short time at a ceremony, so please understand that it has been worn by a child before purchasing. Here's a description of the product: The slightly wide silhouette of the jacket makes it easy for children to wear, even when paired with shirts or blouses. It's a recommended item for ceremonies such as entrance ceremonies and graduations! It's made of polyester, which is wrinkle-resistant. It's also easy to care for at home, which is a great point! It's recommended to wear it as a set-up with the matching Lanatec tapered pants or Lanatec shorts! The innerwear can be a simple shirt, or a frilled collar blouse to layer the collar, which is very cute.
