Wow! A lot of those brought back memories of past Halloween costumes.
When I was 5 years old, my Mom had dressed me up as Clarabell from the Captain Kangaroo show. The costume wasn't plastic, except for the mask. It was an actual cloth material type costume, and it even came with the horn and the red wig.
I remember a lot of those famous icons as shown (Herve V (the midget on Fantasy Island): Scott Baio, Jaws, Farrah, and so many others!) since I was a 1970s kid. Brought me back memories.
I actually wore a "Lucy" (from Peanuts) costume when I was in elementary school (about the 2nd or 3rd Grade).
