Following are depictions and portraits of boys and girls from the Middle Ages and Renaissance. Because the goal of this survey is to provide useful information on a realistic view of children's clothing, I have avoided most allegorical or overly anachronistically-dressed children. I've also included links to extant clothing worn by pre-17th century children.
Take a look at the BNF's online resources for L'enfance au Moyen Âge for late medieval (mostly 15th century) examples, or Children's Portraits for more 16th-19th century examples. More discussion on this topic at the Garb The Child LiveJournal Community . For 17th century examples, see Costume Focus 1660-1715: Children Research Gallery .
