     Working as a manager in the head office of a bank, as I do, clothes can be a nightmare. In

New York, where I worked for a time last summer, you have to brave the burning heat every

time you dare to go outside, yet freeze once you arrive in a meeting with the air-conditioner

turned up. I struggled to know what to wear. The problem was worsened by the office dress

code for the months of July and August, which was "dress-down".

     The dress-down phenomenon seems to have begun in places where staff work through the

terrible heat of summer while their families take shelter at the coast or in the hills. Dress-down,

limited to Friday, allows staff to head straight for their out-of-town places on Friday evenings

without going home to change. But in New York it has now become a week-round state of

affairs. This move may have been born out of consideration; to allow people on Wall Street to

travel to work in the heat in something more comfortable than a suit, but the effect is less kind.

     For me, dress-down is bad for two reasons. The first is that it actually requires a whole new

wardrobe. For my male colleagues in the US, it seemed to mean a switch from one uniform to

another. I basically only own two types of clothes; suits for working in and truly casual clothes

for relaxing weekends in the countryside.

     Returning to London, I was therefore rather embarrassed to discover that my employers had

started summer dress-down. Here too, though its relevance to the climate is far from immediately

apparent. At first, I tried to sidestep it by simply turning up in my suit as usual, but my staff

complained that they then felt pressured into doing the same. So, I found myself having to buy "

smart casual" clothes specifically to wear to work; a ridiculous expense.

      Even more annoying is the fact that I'm still required to have a suit hanging up in my office in

case I'm suddenly called to a meeting on our conference floor, where dress-down is banned for

fear that a client should witness it. One of my colleagues started to accumulate more and more

very smart suits in her office, explaining that she was having her flat renovated and that in-office

wardrobe was a necessity as she was staying at a different friend's place each night. We weren't

convinced.

     For the other great inconvenience of dress-down for the staff is that it makes it easier than

ever to spot when colleagues are going to job interviews. For the rest of the year, it is easy enough

to arrange these during the working week, but in the summer when dress-down rules, it's a dead

giveaway to arrive in overly smart clothes and then go out for a "dental appointment". I would

normally applaud this state of affairs, as an important part of my time is spent trying to prevent

valued employees from moving elsewhere, and any clues about their intentions are helpful and

allow me to nip things in the bud(消灭于萌芽中).

      However, the clothes hanging in my office are now finding a second use. I have suddenly

become the target for several "headhunters", people employed by other companies to try and

attract employees away with offers of better pay and conditions. The only problem with this is

that I have just the one suit at the office. As a series of interviews with one future employer

progresses, I'm having to bring in additional clothes. I can hardly present myself as a highly-paid

investment banker, requiring a vast salary, if they only ever see me in one suit. At this rate, I shall

have to tell my staff that I, too, have decided to have my flat done up.
