Is it true FIE is banning shorts and sleeveless sweater in World Cups ?

Hi all. Recently, a close friend, international foil fencer, told me that during Hong Kong World Cup in January, officials were all around the venue, asking fencers to wear pants and hoodies or fencing suit to cover their legs and arms during warming up. One of the official was from Iran, and he went to see my friend to ask her to cover herself. She was surprised and asked to see the rules, and she discovered that FIE approved this new rule in November 2025 Congress. Any info about this topic?
