What do you guys do with clothes you no longer wear?

I've been going through my wardrobe lately and realized I have quite a few clothes I don't really wear anymore, but they're still perfectly usable.

Got me wondering what do you guys usually do with clothes like that?

Do you donate them, give them to friends/family, sell them, give them away online, or just keep them because you might wear them someday?

Just curious how other people deal with this.
