What to wear: While I realise you might not have a utility gilet laying around, you can switch it out for a regular waistcoat in a dark colour if need be. (People will still get the idea, I promise). Layer it over a dark, long-sleeved shirt and pair with jeans and boots. Once you toss a whistle around your neck and steal a tiny raptor stuffed animal from your little cousin, you'll be all set!
