Schoolgirl uniform (セーラー服, sailor fuku / 制服, seifuku) is a costume tag that's deeply embedded in Japanese manga and doujinshi culture. It refers to the iconic Japanese school uniforms — either the sailor-style (sailor fuku) or blazer-style (seifuku). This tag is significant because school settings are a common backdrop for many genres, from romance to fantasy. The uniform itself has aesthetic appeal in illustration, and artists often use it as a visual shorthand for youth and innocence. It frequently appears alongside 'lolicon,' 'sole female,' and various school-themed parody tags.

DILF (Dad I'd Like to Fuck) is the male counterpart to 'MILF,' referring to mature male characters, typically fathers or paternal figures. In doujinshi, this indicates content featuring older men, often with younger female partners. The appeal lies in the character's maturity and experience.

Pantyhose (パンスト, pansuto) is a more specific variant of the 'stockings' tag, specifically referring to full pantyhose rather than thigh-highs. The tag has a dedicated following who prefer the smooth, uniform look of pantyhose over separate stockings. It frequently appears alongside 'schoolgirl uniform,' 'big breasts,' and 'sole female.'
