USA Swimming has revised the USA Swimming interpretation regarding the use of 2 swimsuits during competition. Special Notice Regarding National Championship Meets: The Rules & Regulations Committee has issued an interpretation that only one suit swimsuit is allowed during competition.  A further clarification provided an exception and allowed that a second suit worn for modesty or support purposes would be allowable and would not be considered a second suit.  However, under FINA rules, as currently written, there is no exception for the wearing of a modesty or support type apparel as a second suit.  For the purposes of our National Championship Meets (US Open, National Championships, Junior National Championships and Trials Class Meets) and our Grand Prix Meets, in order to strictly conform to current FINA rules, no additional swimsuits or apparel may be worn during the actual competition (a race) at those meets.  The use of only one swimsuit of any kind during a competitive race will be enforced at all National Championship Meets.
