Uniqlo long-sleeved T-shirt set of 2 Sizes are 90cm and 100cm. Red (wine red) and navy border. 100% cotton, soft and comfortable fabric. Perfect fabric for this time of year. Both have shoulder buttons. Used sparingly as they were for weekends. The 100cm one has a faint white line on the stomach area (see image 8). How about matching outfits for siblings? For those who understand that these are used children's clothes, thank you. ◡̈
