In general: Size two can fit children ages 1-3, size four can fit children ages 3-5, and so on and so forth. Please size up or down according to your child's size.
We recommend washing in cold water, on the delicate cycle. Tumble dry low heat.
True to size and so soft! I can tell it is a quality material as well. I bought the 2T...My little is still too young to wear it right now, but can't wait to have her try it on! It will look really cute as an oversized tee :)
