My 22 yo DS has got a 12 week internship this summer at a high end strategic comms firm. Think Brunswick but smaller. From my days in the city I think of them as being the last vestiges of the smartly dressed - suited and tied, for men. Them and barristers. Is that still the case? Does DS need navy suits/pale blue shirts/discreet tie/black oxfords or have they gone more casual and if so what is the smart young man expected to turn up wearing? As much info as possible would be very welcome. I think this is an extended interview for a grad job (he is final year next year) so I want him to get it right. Thanks very much.
