10. Dresses for boys
From the 16th century and until around 1920, it was customary for little boys up until a certain age (4-8 years) to wear dresses. The main reason was perhaps the high cost of clothing: dresses were easier to make “to grow into.” The tradition didn’t bypass even royal families: this photo depicts Alexei, the son of the Russian Emperor Nicholas II, in a dress similar to those worn by his sisters.
