This portrait shows the Prince in 'coats' (that is a skirt rather than breeches). In other respects he appears quite grown-up and manly: he wears a sword and holds a baton of command. This and his appearance suggest that he is just of an age to be 'breeched' (though this has not quite happened yet) - seven or eight years old and that the portrait therefore dates from c. 1658.

The Prince is shown in orange coloured costume, a deliberate (and common) way to allude to his title, the Prince of Orange. He wears the ribbon of the Order of the Garter (awarded in 1653). The feathered hat resting on the table to the left was added later, when the painting was extended. This would appear to be an indifferent copy of an original, probably by a Dutch artist.
