I've heard that once you're down about 10%, you and other people start to notice. I've just crossed that, and I haven't gone down any clothes sizes, but my shirts are definitely fitting better, and I don't feel like the button is going to go popping off my pants and shoot across the room (which has happened, by the way - that was fun).
No one has noticed, but since I'm short and really big, I figure it will take a bit more for that to start to happen. I shouldn't say no one - my wife has definitely noticed. Recently during happy happy fun time, she was pleasently surprised at how much...um...I'll just say "closer" we could get.
