We bought 2 sets one for our daughter and she will be 3 next month but bought her 4-5 it fits great there is room to grow and our 11 year old son is 10-11 but the shirt didn't fit at all and the pants fit like leggings (which he likes) but they shouldn't fit like that. You need teddy bear pajama sets to be available and for adult sizes see below.
