Color: Blue Pattern: Other Length: Midi Material: Cotton Season: Spring, Summer, Autumn This is a Comme Ça Fille kids' shirt. It's made of fabric that looks like it has blue woven into it. It was worn once, then dry-cleaned and stored at home. It's folded with cardboard backing, and I haven't taken it out of the bag because I think it's safer to buy it this way for hygiene reasons. Therefore, I can't confirm the tag, but it's probably made of cotton.
