Utterly Casual Yacht Wedding

My question is about an utterly casual yacht wedding.

My boyfriend and I are invited to a wedding taking place at sea on a yacht. What do we wear? What should we know about a yacht wedding? The dress code is Utterly Casual. Since there are 150 guests we don’t want to be underdressed or overdressed. We’re not sure what Utterly Casual means for a wedding on a boat!

I can’t think of anything more fun than an utterly casual yacht wedding.

You can assume that the bride and groom will be dressed casually, but more formally than their guests. They want everyone to relax and have a good time.

Most important is footwear. Shoes should be broken in so they won’t slip or slide on slippery high polished flooring. Don’t wear spiked heels that could damage any wooden floors.
Your boyfriend would wear a navy blue blazer or any lightweight linen jacket, a collared open shirt and dress khakis, colored or white trousers with possibly a rubber sole shoe. A tie would be optional.
As the bride will be dressed super casually, you wouldn’t want to wear anything that might be dressier than what she’s wearing. A jumpsuit would be terrific or any dress that moves well in the wind and on the dance floor that’s not puffy with fabric or tacky with sequins.

It goes without saying that sunscreen and a hat are a must for a daytime wedding at sea.
