I have to go to a memorial service. I don't think people dress as sombrely as at funerals, but it's so long since I've been to one that I looked on the web.
"What to wear at a memorial service. Tips and warnings:
1 Only wear t-shirts as an undergarment.
2 A wide-brim hat is okay but not a trucker's hat. You can add a flower in it if you desire
3 Never wear flip-flops to a memorial service.
4 Avoid sundresses that are bright in colour or have patterns. They will look gaudy at a memorial service."
Flip flops with my orange sun dress and an Eddie Stobart cap are out then?
Lucky I checked.
