-Comment: I think at least 2 boys in sailor suit looking jackets. I don't know their names. Boy on top is the same as on bottom left. Directed by Günther Meyer, novel by Wolf Durian. I don't like most East German films, but this is one of my favorites. I haven't seen it for years and I even had recorded the documentary "Kai für Kiste gesucht" about the casting. Main character is the 13 yo Christoph Zeller as Kai (I think the red page boy). I have to check this again. Very good film, but for "sailor suits" only rating 5 for now. I didn't knew that there is also a 1960 film, but haven't find any pics or clips of that. Good plot about advertising bubblegum and this Berlin kids' gang.

Update: After checking some more parts of it, I will upgrade from 5-7. Very interesting historic clothes (also grown ups, incl women). And also a boy in breeches and boots (pic bottom left).
I still have to check it completely especially for the collar of the 2nd boy (pic bottom right) but I assume rather few (good) sailor suit (and very few breeches) scenes.
