Clothes donation

Hi guys. M 22 here and I'll be leaving mysuru in the next few months, after 4 years of training here. Question is, I have a lot of clothes that I'm not planning on taking back with me. They are all in really good condition and I will definitely be washing them before i give them for donation. Question is, where do I donate them? I've outgrown most of them and they would easily fit a male aged anywhere from 16 to 25. Please let me know where/ who I can contact to give them away. Thanks!
