I attended the final day last year in Ardmore and wore chinos, a polo, and rubber soled monk straps, which let me walk the course without damaging better shoes or needing to wear to sneakers. That said, as GBR said, your corporate tent affects how you should dress yourself.
Likewise. As far as value proposition goes, Cantarelli is one of the best in the world, but I am far too tall (6'4" 193 CM) to wear anything that the company produces, which is too bad. I really love the construction and the shape, but I would need like a double extra long to even be close.
