This category includes things that you yourself will never know for sure and which you can not sell. In no case do not throw them away. Some of the things can be donated or distributed to family members, friends, acquaintances or colleagues.
The other part can be given to the needy through charitable organizations ("Thank You", "Dump" stores, Charity Shop). It's easy - just find the container closest to you for taking things and drop your good there.
Even if the thing has defects, it can still be useful.
A part of things with defects charitable shops are allowed to be recycled. This allows you to reduce waste in the textile industry.
And you can also arrange a swap-party - a meeting to exchange clothes. This is the perfect way to update your wardrobe completely free of charge, get rid of boring things and spend time in a good company. The rules of swap-partying can be very different. You need to choose the optimal combination of ideas that is right for your company.
Remember: things are just things. It does not matter how much clothes you need for happiness. It is more important to treat it properly, take care of it and store it in a way that makes it comfortable for it.
