Children of all classes wore miniature versions of their parent’s clothing. Boys wore petticoats until the age of 5-7 years when they were ‘breeched’.
All the images displayed are British (as far as I know). Dutch genre paintings are not included as it is uncertain that the same style of clothing was worn there at this time (1620-1650).
