It was only from the 19th century onwards that we started talking about children's clothing: over the previous centuries, indeed, after the first two or three years in which it was usual for both sexes to wear the same dress, children were dressed and styled identically to adults, a choice considered essential to accustom the little ones to the role they would have held in the future.
The new childcare theories that began to spread in the late eighteenth century, thanks to the French philosopher Rousseau, however, explained how games and freedom of movement were essential for the correct development of the child: it is precisely in this era, therefore, that we begin to conceive a specific clothing for their age, while taking up the styles and decorative motifs in vogue in those days.
The boys wore shorts, and soft tunics, and furthermore, a type of clothing particularly in vogue for children of both sexes in the late nineteenth and early twentieth centuries turned out to be the sailor suit. Typically dark blue or white, made of comfortable and resistant materials, it adapted to the movement needs of the little ones.
