Im bumping this as i dont want to create a new topic (and being told later that i dont use the search function:P)

So im going in a wedding next week and i have no idea what to wear. I guess jeans are out of the question and also black dresses are out. A suit (if i can find anything that is!) is appropriate? I live in Geneva by the way so dont recommend me stores somewhere else :P

Also, the only person i will know there is the friend i will be going with. Is there any etiquette i need to follow or my job is to stand next to him and look cute?

Thanks
