Me and a friend (who I'm trying to get to register on here) donned morphsuits and bocks for the Old Basing carnival. There was a chap from the local paper taking photos and I managed to sneak a trick in there.
We were meant to have the hoods up and the alien eye sunglasses over the top, but that limited our visibility to about three inches in front of our faces, so the last-minute skull cap and glasses approach was adopted.
