Members of The Church of Jesus Christ of Latter-day Saints criticised Brigham Young University's women's cross-country team uniforms on social media, arguing that the sports bras and athletic shorts violated religious modesty standards. The backlash, which garnered over two million views on X, highlights ongoing tensions between the university's NCAA Division I athletic standards and the strict dress code enforced by the Mormon Church, which sponsors and funds BYU. The criticism centres on the perceived incompatibility between standard athletic uniforms and the church's expectations for modest dress that accommodates the "temple garments"—special undergarments worn by many practising Mormons.

BYU's institutional dress code permits modest athletic wear and states that clothing should accommodate temple garments as a guideline. However, critics argued that the university should maintain higher standards than secular institutions and suggested alternative uniform designs that would work with the religious undergarments. The controversy reflects broader ongoing discussions within the Mormon Church about balancing athletic participation with religious principles, particularly as enforced by church leadership—traditionally male and middle-aged—who have emphasised modesty standards as essential to young women's "eternal future."
