These garments represent clothing worn by non-binary humans in history (we have specifically omitted universal clothing components, such as cloaks, to ensure any representation is in full clothing for non-binary individuals.) In some cases, these may be clothes worn by a recognized non-binary gender in a specific culture, in others, it may simply be clothing that was worn by all humans in the culture and therefore is appropriate for all to wear
Remember that the SCA does not require your clothing to match your gender/culture/social status/relationship status or any other factor of you regular life. See our FAQ for more information
