What is required for undergarments worn under a singlet?

The requirement for undergarments worn under a singlet being tight-fitting is based on the need for functionality and safety during wrestling matches. Tight-fitting undergarments help prevent any interference with the singlet itself, allowing for smooth movements and reducing the risk of accidental exposure.

Additionally, loose undergarments could potentially cause a competitor to be at a disadvantage by getting caught during grappling, which could affect their performance. This standard helps maintain the integrity of the sport while ensuring all competitors adhere to similar guidelines for uniformity and discipline during matches.

Choosing options that suggest brightly colored or longer lengths wouldn't align with the focus on practicality and safety that governs wrestling attire rules. Therefore, the emphasis on tight-fitting undergarments upholds the sport's regulations effectively.
