Gloves or mittens may be worn during warmups, but usually are not worn during a competition. Skates should be cleaned and polished for every competition. Hair should be done tidily and securely. Bobby pins, scrunchies, rubber bands, etc, if used should be very securely placed. These items present a hazard to skaters if they should fall off and lay on the ice.
Emergencies do happen and it's pretty nice to have an option available.
If you don't bring a spare outfit, girls should at least bring a few spare pairs of tights, and all skaters should have spare laces available. Competition Conduct Remember, every child competing is special to someone. Skaters and families should be respectful of all competitors. In the audience, refrain from entering, exiting, or wandering the bleacher area while skaters are performing. There's plenty of time in between skaters to move around.
