How to donate clothes? (Kuala Lumpur)

Hi

I have a load of clothes that I want to get rid of and it feels wrong and wasteful to just throw them away (a lot of barely or never worn items) - if I was at 'home' I would normally just bag these up and put them in the donation bins but I haven't seen any here in KL - is there such a thing (if so where) or can someone suggest where else I could dispose of these?

thanks in advance.
