What to wear?

Several folks have asked about what one wears to a wedding ceremony on a boat. Well, remember that it will be on a boat, in upstate New York, on a river, in the fall. It could be 85 or 35 degrees.We could have sunshine or monsoons. Wear what makes you comfortable. Layers may be beneficial. I would suggest that you wear shoes that add to your sure-footing... and that allow you to boogie!
Ultimately, we don't really care what you wear. We just care that you come!
