The modern campaign for bodily parity gained institutional momentum through the Free the Nipple legal battles of the 2010s. Activists stopped pleading for special exemptions and began filing federal civil rights lawsuits grounded in the Fourteenth Amendment. Their central argument was simple: enacting a law that permits men to expose their chests while arresting women for the exact same conduct constitutes unconstitutional sex discrimination under the Equal Protection Clause.
The landmark breakthrough arrived in 2019 when the 10th U.S. Circuit Court of Appeals ruled in Free the Nipple v. City of Fort Collins. The federal appeals court struck down the Colorado city's public nudity ordinance, affirming that moral squeamishness and outdated gender stereotypes cannot justify discriminatory penal codes. That ruling established binding precedent across six states: Colorado, Wyoming, Utah, New Mexico, Kansas, and Oklahoma. In those jurisdictions, municipal bans targeting female breasts specifically violate the U.S. Constitution.
Other federal appellate circuits refused to follow suit. The 7th and 8th Circuits previously upheld municipal public decency ordinances, ruling that cities possess a legitimate government interest in protecting community standards and traditional moral sensibilities. Because the U.S. Supreme Court has repeatedly declined petitions to resolve this circuit split, the constitutional right to topfreedom remains geographically fractured.
