Here's a great article, courtesy of Faconnable that you should read if you plan to attend the Monaco Boat Show.
Façonnable’s Fall/Winter 2010 menswear collection provides a way for you to wear one outfit that will add sophistication and class during the day and carry you through to the evening without feeling too under-dressed.
Try wearing these Flat Front ‘Milleraies’ Corduroy trousers in Brown. They are a great compromise and are far smarter than jeans, but not quite as formal as suit trousers. Team these with a plain black top like the Classique-Fit Long Sleeve Tee in Black. As outerwear during the day, opt for the Classic Lightweight Shirt Jacket in Brown. The black and brown contrast contributes to a statement smart casual balance.
To accessorise, wear some smart black shoes like these Richelieu Dress Shoes, look for a matching belt like this Distressed Leather Belt in Black that will contrast with the brown trousers. To accessorise the look further during the day, add a chunky brown scarf for warmth and to add more of a focal point to the outfit."
