All sizes are 110. I'm selling these because my child has outgrown them. There are two more photos of the black innerwear. I tried these on my child with winter clothes, but they were too small, so they're currently being washed. The black innerwear includes one Uniqlo Heattech, and items from GU, Shimamura, and Nishimatsuya. The items from brands other than Uniqlo were sold as warm innerwear (like Heattech, which is how we used them). The second photo shows two items that are in good condition because they were never worn.
