How Halloween Costumes Got Sexy in the 1970s

For most of the 20th century, Halloween costumes fell into two camps: genuinely unsettling monsters or wholesome cartoon characters bought off a department store rack. There was no in-between, and definitely no skin showing.

Store-bought costumes through the 1950s and 60s were boxy plastic masks paired with smocks printed with superheroes or ghosts. The goal was recognizable fun, not personal expression, and certainly not anything provocative.

That started shifting hard in the 1970s, when three cultural movements collided at once: second-wave feminism, the sexual revolution, and the rise of gay pride parades in cities like San Francisco and New York.

These parades turned Halloween into something new entirely: a public street party where dressing outrageously was an act of defiance, not just a kid's game. Adults reclaimed the holiday for themselves.

In cities with visible LGBTQ communities, drag and gender-bending costumes became centerpieces of Halloween night, pushing boundaries that mainstream costume shops had never touched before.

At the same time, feminist movements were loosening rigid dress codes and reshaping what women could wear in public without consequence, which bled directly into how costumes were designed and marketed.

By the late 1970s and into the 80s, costume companies noticed the shift and started producing skin-baring adult costumes on purpose, turning what began as grassroots liberation into a permanent retail category.
