We are invited to a formal destination wedding in Barbados next month. They told us it will not be on the beach, but we’re not really sure if it’s outdoors or indoors. Does my husband have to wear a Jacket? And will a short-sleeved dress shirt pass? It’s hot and humid there and he is balking at long sleeves and a tie. I thought it was weird that the invitation didn’t say if it was outdoors or not.
