space print
When something, usually an article of clothing, has such a print that it resembles outer space.
Space print implicates starry sky print to simplify the relation between both tags, as they share many of the same features. The space print tag is to be used for prints that include celestial bodies other than stars, such as planets or nebulae, or otherwise don't represent a view that could be seen from the surface of a planet. A simple print with only stars should only get the starry sky print tag. (Danbooru topic #13462)
