DH is travelling to NYC, Florida and Texas on a business trip in November. Apart from " a dark suit" I can't find much advice on the net about what he should wear. It's a pretty traditional sector ( think attorneys) and he will be at meetings and conferences in the day and dinners etc in the evenings. He needs to make a very good impression but he naturally tends towards a slightly scruffy /eccentric /academic look,which I'm not sure is quite right for the Us market IYSWIM
So it's the details I'm looking for please.Is the dress code similar to the Uk or different in subtle ways?
Does the shirt have to be white or light coloured? Do ties need to be very consevative? What does he wear in the evenings? How cold will it be in NYC and what does he wear over his suit? Casual jacket or a woollen coat? Will it snow and if so, what footwear is suitable?
He normally carries all his paperwork, laptop etc in a rucksack-is that ok or will it be seen as too casual /scruffy?
