I dressed my child, who was born in June, in these for one season. The breathable mesh material was very useful in the summer. Uniqlo's fabric is also sturdy and doesn't get worn out, and I thought the feel of it was better than Nishimatsuya. I'm currently pregnant and think these will be perfect for my baby, who is due next spring. There is some yellowing around the neck.
