Hi everyone....This is another post about wedding attire. I will be attending a wedding in June. It's going to be held on a yacht sailing from NYC for the evening. I was wondering what your suggestions are for attire. I am a 23 year old guy and most people at the wedding should be in their late 20's to early 30's. The invitation said "formal attire" but everyone has different standards of formality. Thanks for your help.
