What should I wear when officiating?

LSA's standard dress for technical officials and officials (Section 13.5):

• White or navy blue shorts, slacks or skirt.
• White shirt or blouse, and a white or navy blue sweater.
• Protective clothing is allowed in bad weather.
• White caps or hats for sun protection are strongly recommended but not compulsory.
• If the organiser provides an event uniform, or the LSA authority requires coloured garments for specific roles, wear it.
• Sponsor-branded apparel is allowed only with the LSA authority's prior approval.
• No club identification. Cover it if possible, or you may be removed from duty.
• Some officials (e.g. water-based judges) may wear costumes or wetsuits.

You are also encouraged to protect yourself from the weather with eye protection, suitable footwear and sunblock, and to avoid keeping competitors standing exposed to the elements for long periods.
