Dark gray jacket and pants set. - Color: Dark gray - Style: Jacket and pants set - Design: Two-button blazer Thank you for viewing. This is a formal top and bottom set from Uniqlo. The size is 100. I bought it for Shichi-Go-San (a Japanese festival for children). The fabric is jersey-like, so it's easy to move in, and I think it won't be constricting for small children. The item was only worn for about an hour. The waist is adjustable, as shown in the photos. I am happy to combine shipping with other items and consider price reductions, so please feel free to ask.
