Below is a list of sizing charts by brand. When measuring to determine what size your child will need it is best to measure an outfit that fits him/her instead of trying to measure your child. The reason for this is because the measurements provided for the outfit are while the dress or romper is laying flat. You will get a more accurate measurement to compare to the size chart if you take measurements the same way. If it is a boys romper you are trying to measure, just lay the outfit flat on a hard surface and measure the outfit from the back of the neck to between the legs and this will give you the shoulder to crotch measurement.
