My grandson loves the Trotters button down shirts. He just turned 3 and we ordered him the 4/5 and it fits very well with a little extra room. The colors of the zoo shirt are very cheerful and the quality of the fabric is pure luxury for children’s clothes. We are going to order a few more. He can wear this to school or for dress-up. The Liberty design is very intricate and fun to identify the animals. The teachers at school love this and also his Trotters dinosaur shirt.
