DS has a summer internship with a well known consultancy firm in their London head office. He will turn up in a suit on day 1 but is hoping it'll be jackets and ties off after that. Is that likely to be the case?
Also, he only has 2 suits - black and navy - which aren't summery. Are the men likely to be in lighter colours?
He was wondering about getting a linen suit but, in my experience, they always look more casual and creased.
