Outfit for the PIR The going consensus is that the attire is business casual, though there is currently no enforced dress code, so jeans and a tee are welcomed. But really? Your new Sailor will be in his/her *formal* Navy attire, please dress accordingly!
Your new sailor will be in their dress whites or dress blues. Think of how you will like to look standing next to them in the many photos that will be taken.
Also, wear sensible shoes. You will be doing a bit of walking. The drill hall floor can also be a little slippery. You don't want to take a fall after the ceremony while running (and do not not run!) to hug your sailor.
