The German Historical Museum, the Stiftung of the Haus der Geschichte der Bundesrepublik Deutschland and the Bundesarchiv have a nice website called the Living Museum Online, or LEMO. It combines facts about the eras in German history with eyewitness reports, multimedia and objects for exploration.
The postwar eyewitness page is here. All in German, but there’s still much to explore even if you don’t know the language. The photos and videos are also worth a look. And if you want a look at those trousers, try the 360-degree objects page.
