According to Cindy Benkowski, owner of Just Kidding in Whitefish Bay, nine out of ten of her customers buying for kids other than their own children don't know the size they need. To add to the confusion, sizes and fit vary from manufacturer to manufacturer. Sizing for American designed clothing differs for infants and toddlers. When buying for an infant, take their age in months and double it. For toddlers, take their age and add one year.
European sizes are more true to size for toddlers and infants.
Keep in mind whether you want the child to wear the outfit immediately or if it will be saved for another time of the year. A knowledgeable sales staff is a real benefit. In most cases they know their merchandise well enough to help make sizing suggestions. Many people don't see the child on a regular basis especially if they live out of town. If you're still not sure we recommend going up to the next size.
