This is a Coola Cool T-shirt. The size is 80. It's a cute outfit with a pink floral pattern. It's made of a fabric similar to a romper, so I think even a 0-year-old baby who is just starting to wear separate clothes can wear it. Of course, it's also very cute for 1-year-olds, and the fabric feels nice. It opens and closes with snaps on both shoulders. Easy to put on and take off!
