You can donate old clothes at various places depending on your location and preferences:

• Charity Clothing Donation Centers: Many cities have clothing donation centers where donated clothes are sorted and given to those in need. For example, in Hamburg, there are several "Kleiderkammern" where clothes in wearable condition can be donated

• Charity Shops and Organizations: Organizations like Oxfam and the Salvation Army accept clothing donations. Oxfam shops accept clothes for resale to fund their work, and the Salvation Army accepts clothes in good condition as well as worn items for recycling

• Donation Bins: Many cities have donation bins, often near supermarkets or in neighborhoods, operated by charities or organizations like the German Red Cross or FairWertung. Clothes should be clean and suitable for the current season, and shoes should be tied together

• Specialized Charities: Some charities focus on helping specific groups, such as homeless people. For example, in Berlin, Berliner Obdachlosenhilfe and Berliner Stadtmission accept clothes to help the homeless

. In Düsseldorf, the Gute Nacht Bus is a recommended option for donating clothes to help homeless people

• Postal Donations: Some organizations, like Deutsche Kleiderstiftung, allow you to send clothes by post free of charge if the package is over a certain weight (e.g., 5 kg)

• Retail Take-Back Programs: Some retailers offer clothing donation or recycling programs, such as H&M or Dunelm, where you can drop off clothes in-store for recycling or reuse

• Local Recycling Points: Many supermarkets and local car parks have textile recycling banks where you can drop off unwanted clothes and textiles for recycling or reuse

When donating, ensure clothes are clean and in wearable condition unless the organization accepts worn items for recycling. It is advisable to check with the specific charity or donation point for any particular requirements or opening hours

. If you want to donate in a specific city or country, local charity websites or municipal resources often provide detailed lists of donation points and procedures.
