[Oh, okay, I see. I had thought it might be a scarf because I thought could see his shirt peaking out near his shoulder, but I think it's just the light hitting the liner.Wow, I was way off on this one. Francois Verkerk?I believe Bows actually uses him as his avatar. And Bows picture comes up when you google "Stephan Schneider scarf".
Browsing through the thread, I first thought this model was wearing a weird/cool robe styled sweater. On closer inspection, I realized it was his scarf.
A little disappointed it's not a sweater. A kimono/robe styled sweater would sound cool, wouldn't it?
Anyone? Just me? Okay.
He seemed to specify no tuxes. A suit and tie would still be less formal than a tux. He also expected a lot of people to not wear suits, but I don't know if that is to mean it is a casual wedding, or that he just assumes it's a casual wedding. A little more info might be helpful.
I don't like your outfit at all, by the sounds of it. Tan isn't formal enough, and neither is a window pane jacket. Wear a suit. In linen, if possible. Wear a tie, but if most people aren't wearing one, you can take it off.
