These are short-sleeved undershirts from UNIQLO and Nishimatsuya. I bought these for my daughter, who was born in June of this year. The temperature quickly rose, and she hardly had a chance to wear them, so she only wore each one 2-3 times. There are 3 from UNIQLO (cotton fabric): Beige, a giraffe illustration, and a bear illustration. There are 2 from Nishimatsuya (mesh fabric): White, and a pink one with a cherry pattern. All are 100% cotton and size 50-60cm. They have been washed with baby detergent and stored.
