Cute outfit and fit nicely. My 4 month old wears 6-9 months and it was perfect although others complained of it being sized small. Only disappointment is that I got it 2 days ago, washed it yesterday,  put it on him today and it already has a hole at the seam. Doesnt seem to be made real well and the cotton is basic. Washed in cold with Dreft and black is already faded.
