The wrong trousers and old clothes

What do you do with your old clothes? I guess many of us take them to charity shops if they're in a reasonable condition. I'm not certain there's an equivalent in Germany so let me know if I'm mistaken.

I did come across something about collecting clothing on a German church website

Was tun, wenn die Hosen nicht mehr passen oder einfach nicht mehr modisch sind. Bloß nicht wegwerfen, sagt Bettina Körtge vom Diakonischen Werk Jerichower Land. Tragbare Kleidung nimmt die Diakonie in Burg gerne

Burg is a town in Sachsen-Anhalt. There's an audio report accompanying the piece so take a look at http://www.ekmd.de/aktuellpresse/nachrichten/20018.html and learn German words about to do with helping the needy - Bedürftige
