Females wearing a one-piece singlet must wear what type of undergarment?

The requirement for females wearing a one-piece singlet to use a tight-fitting undergarment is based on the guidelines set forth in wrestling regulations to ensure both comfort and competitiveness. A tight-fitting undergarment supports the athlete adequately during a match, allowing for mobility while minimizing the risk of any wardrobe malfunctions that might arise from loose-fitting options. This snug fit is also instrumental in providing support, particularly for athletic movement, which is essential in a sport as physically demanding as wrestling.

Additionally, it adheres to the standards of sportsmanship and fairness in competition, as it creates a uniform appearance that is both respectful and professional. This aligns with the sport's emphasis on proper attire, which is designed to promote safety and performance. In contrast, loose-fitting undergarments could lead to distractions or concerns regarding fairness due to the potential for such garments to shift during matches. Similarly, while a casual sports bra might offer support, it does not fulfill the strict criteria of being a tight-fitting undergarment stipulated in the regulations.
