With a focus on clothing, bodies, and emotions, this article examines girls’ First Holy Communions in twentieth-century Ireland (c. 1920–1970), demonstrating that Irish girls, even at an early age, embraced opportunities to become both the center of attention and central faith actors in their religious communities through the ritual of Communion. A careful study of First Holy Communion, including clothing, reveals the importance of the ritual. The occasion was indicative of much related to Catholic devotional life from independence through Vatican II, including the intersections of popular religion and consumerism, the feminization of devotion, the centrality of the body in Catholicism, and the role that religion played in forming and maintaining family ties, including cross-generational links. First Communion, and especially the material items that accompanied it, initiated Irish girls into a feminized devotional world managed by women and especially mothers. It taught them that purchasing, hospitality, and gift-giving were central responsibilities of adult Catholic women even as it affirmed the bonds between women family members who helped girls prepare for the occasion.
