As one who has worked professionally here for some time, I still say go for simple. Go for straight or spread collar. Button down and tab are for kids. So long as he is in shape, go for form fitting and lean. Pants? No pleats (flat front only), no cuffs. Try dark to medium pants and blazer. 3 button blazers (with the bottom button undone at all times) are preferable. Shirts and ties should show some color (as he will need people to notice him). I'd say wear a tie the first day, then see what his boss is wearing. If his boss is wearing a tie, wear a tie every day but friday. If he isn't, he should only wear a tie half the time, the other times wearing his top button undone.
Only use pinstripes in an emergency.
