I spent some time over the holidays clearing out stuff and, even though I don't still own a lot of suits and jackets these days, I still have a lot of "business casual" I bought because I would "always use it some point." I'll probably donate a lot of it even the stuff that's never been opened.
This isn't true everywhere of course but a long time ago I worked at a company that had dry cleaning collection of premises. This was a computer company. That would be laughable today.
