"... Therese Alshammar of Sweden..., 31, clocked 25.44 seconds in her qualifying heat at the Sydney Olympic Park Aquatic Centre, shaving 0.02 seconds off the world record she set at a meet in Barcelona, Spain, on June 13, 2007.
But officials later discovered that she was wearing two swim suits, which is no longer permissible under revised requirements ratified last Saturday by FINA, the governing body for swimming.
Meet organizers were not available for comment. ..."
But what if she was wearing a training brief underneath for modesty reasons? From The Australian:
Alshammar, 31, was wearing a brief training suit underneath a racing bodysuit and may be ruled to have breached the new rule which restricts swimmers to wearing only one swimsuit in competition.
The Swimming Australia swimsuit rules allow swimmers to wear a brief suit under the racing suit for modesty purposes but the new FINA requirement, as published at the weekend, is a blanket one-suit-only rule.
