Thank you all very much.
Scroggs; then only reason I asked this forum for help, was that I am affraid I might end up looking like someone going to a funeral wearing a dark blue or black suit... The general dresscode in Scandinavia is a bit more relaxed than it is in UK. Not that I don't have a suit.
And after reading this post I am quite convinced that I will go for the suit.
Thank you again.
