What would be the proper dress for a daytime wedding. It is in a restaurant/reception hall. I believe there will be a sit down meal because we have to choose beef or chicken. The wedding is on Halloween and is a whimsical inviation with many halloween jokes such as bubbling brews and frog legs immediately following. The only reference to dress is no costumes allowed. The bride and groom wanted costumes but the bride's father who is paying vetoed it. I'm especially concerned about dh who doesn't currently own a sport coat. He has one fairly formal pin stripe suit which depending on his current weight may or may not fit. I don't want to dump a ton of money on clothes for this.
