Throw! If you have special "memories" of a particular item, put it on now and get a photo of it, with you looking gorgeous inside it! Or make it into a craft item, a handbag or something. Keeping larger clothing for me always gets me thinking that I can put on a little weight ... etc.

And don't think ... do I want to throw this item, think instead - Do I really WANT to keep this item. It puts things into perspective!
