Primetime Emmy Award for Outstanding Period Costumes
The Primetime Emmy Award for Outstanding Period Costumes is presented as part of the Primetime Emmy Awards. In 2015, categories for period/fantasy and contemporary costumes were created. The categories were divided in 2018 for period and fantasy/sci-fi costumes. They replaced the retired categories for Outstanding Costumes for a Miniseries, Movie, or Special and Outstanding Costumes for a Series.
Rules require that nominations are distributed proportionally among regular series and limited series/movies, based on the number of submissions of each. For instance, if two-fifths of submissions are limited series/movies then two of the five nominees will be limited series/movies.
