This pattern includes sizes Newborn-2T. It can be adjusted to fit a 3-4T if you use worsted weight (4) instead of sport (3), but note that the skirt will come out heavier. If you choose to use worsted weight. I was inspired to write this pattern for my 2 year old daughter. There are bloomers that are attached to the skirt.
