Objective Mainstream American perception often views Islamic headcovering as a controversial practice indicative of gender repression and norms violating individual rights. Practicing Muslims counter that headcovering expresses piety, modesty, and protection. Recent scholarship affirms the complexity of the practice, and reveals that the motivations behind donning the headscarf span the religious, social, and political realms for Muslim women. Methods We explore the motivations for the practice among American Muslims, examining the way religious, social, and political life interact and reinforce one another, using data from an online survey of 1,847 Muslim‐American women from 49 states. Results Our findings demonstrate that religiosity is not a monolithic factor, and religious practices interact with and enforce headcovering in complex ways. We illustrate that conventionally understood indicators of Islamic religiosity align along three dimensions: religious lifestyle, religious abstinence, and religious socialization. Elements of a religious lifestyle, such as praying and attending mosque as well as fostering connections with Islamic social networks, are more strongly associated with covering than practices related to abstinence or socialization. Conclusions Ultimately, our research demonstrates a more nuanced understanding of how different aspects of Muslim religiosity condition covering among Muslim‐American women.
