>>2878670If there is one thing the Japanese are okay with doing anachronistically, it's having modern underwear and undergarments in general in their fantasy series. Sometimes they will handwave it away by saying it's magic that makes the clothing fit the wearer perfectly.
My question was more did the kid lift her skirt and get an eyeful of her underwear as well or did he just lift her skirt and see her pants covering her butt. Since they do cover her feet, I'm leaning more to them being modern stockings.
