You have a lot of old clothes, indeed! It was a good choice that you will have everything donated. If you didn't do this clearing-up session on your room, you wouldn't know that there are bunch of old stuff waiting to be disposed. But the difference about this is that, these items can still be used, you just have to find another people who can use such stuff you have. Watching the video makes me cringe because there were unused shirts that are for disposal. You may be spending too much for your clothes.
Thank you for your comment really means a lot and will take your thoughts into consideration, but I make sure all clothes are suitable for donating, and I am cutting down on how many clothes I have, only buying what I truly need.
Clear ups are a time to be out with the old and in with the new.
