Science fiction authors have designed imaginary spacesuits for their characters almost since the beginning of fiction set in space. Often, comic book creators seem unaware of the effects of internal pressure which tends to inflate a spacesuit in vacuum, and draw their imaginary spacesuits as hanging in folds like a boilersuit; this can often be seen in the Dan Dare stories, where the artist often drew from actual or photographed posed actors. Many space story writers merely mention a "spacesuit" without considering or describing design details, in the same way as they mention a raygun or a spaceship without considering how its mechanism would work.
