This is a big-collared dress for kids. The large triangular collar is a very cute feature of this dress. The size is 150cm, but it might be a bit short. My daughter wore it when she was wearing sizes 130-140. The color is white. The material is polyester. It's a smooth and cool material, so she really loved wearing it. There are some minor scuffs and snags. Please check the photos. This is a used item, so there may be some overlooked imperfections. We appreciate your understanding. Big collar Shirt dress
