Next to an 8 yo girl, I also found this very young boy in a rare, light brown sailor suit including matching (angled) collar (2 white stripes) and scarf. Very brief scene set in around 1913 or maybe some years earlier.
Still rating 6 for the movie (but much fewer for the sailor suits).
Quite good and funny movie. Also with some other historical clothes, but rather few good scenes.
Also on my bib overalls blog (13 yo getting spanked, and 2 younger boys), rating 6 as well.
