The basic foundation of the Batsuit is a tight-fitting bodysuit, similar to many superheroes. In early depictions, it was similar to the garb of early 20thcentury circus performers. Batman #1 revealed that there is a ballistic vest sewn into the costume. In modern depictions, the briefs are integrated into the main costume, so that section of the costume constitutes only a seam and color change from the rest of the suit. The bodysuit has varied in color and style as depicted by different artists.
In 1998 writer-artist John Byrne revamped the origin of Spider-Man in the 13-issue limited series Spider-Man: Chapter One (December 1998 – October 1999), similar to Byrne's adding details and some revisions to Superman's origin in DC Comics' The Man of Steel. At the same time the original The Amazing Spider-Man was ended with issue #441 (November 1998), and The Amazing Spider-Man was restarted with vol. 2, #1 (January 1999). In 2003 Marvel reintroduced the original numbering for The Amazing Spider-Man and what would have been vol. 2, #59 became issue #500 (December 2003).
Halloween costumes are costumes worn on or around Halloween, a festival which falls on October 31. An early reference to wearing costumes at Halloween comes from Scotland in 1585, but they may pre-date this. There are many references to the custom during the 18th and 19th centuries in the Celtic countries of Scotland, Ireland, Mann and Wales. It has been suggested that the custom comes from the Celtic festivals of Samhain and Calan Gaeaf, or from the practise of "souling" during the Christian observance of Allhallowtide. Wearing costumes and mumming has long been associated with festivals at other times of the year, such as on Christmas. Halloween costumes are traditionally based on frightening supernatural or folkloric beings. However, by the 1930s costumes based on characters in mass media such as film, literature, and radio were popular. Halloween costumes have tended to be worn mainly by young people, but since the mid-20th century they have been increasingly worn by adults also.
