Don’t take your eyes off the ball after a try, they drop the goals quick, no relaxed wander back for you, kick often taken the ‘wrong way’ from in goal, so keep sharp
Do that. Doesn't have to be a rugby shirt. A bright yellow / orange running shirt would be fine...unless it is the World 7s in which case that will issue you with them!
Thanks for all the comments/advice.
@Coolfork - Regrettably, I've only had 1 season as a ref and only have 1 shirt (and we've not had this seasons allocation yet). However this is white. Hopefully there aren't teams that play in white. I may take a couple if different coloured T-shirts with me just incase.
