The Competition Uniform
There are a number of rules governing not only what is permitted in competition, but also what is required. This includes clothing, bandages, wraps, tape, belts, and footwear.
All of this can be found in the IWF Technical and Competition Rules & Regulations.
However, to reduce confusion for athletes, coaches, and officials, the IWF has produced two additional documents which clearly explain the rules, complete with helpful pictures and diagrams. Any athlete planning to lift in competition should familiarize themselves with both these documents to avoid any last minute surprises.
Note that any deviation from, or exceptions to, these or any other IWF rules in an NSWA sanctioned event will be clearly stated in the registration information.
In particular, most NSWA events permit athletes to wear shorts and t-shirt, rather than the "costume" or singlet.
