Munich - Office workers know that in high summer it can be difficult to dress professionally and at the same time feel comfortable in warm temperatures.

Although women have it easier than men, it's often impossible to achieve both when dressing for work.

"As harsh as it sounds, men of the world wear long sleeves under a suit or sports coat even when it's 32 degrees Celsius," said Georg Stiels, a style consultant in Munich. "Anything else is in fact unfashionable."

Lighter fabrics help stay cool. Linen, however, is tabu in the office even if it doesn't wrinkle so badly. Many textile makers are offering especially light, but still business-like and wrinkle resistant fabrics, typically made of a combination of materials. Also, going without a tie is becoming more and more common.

Stiels said women have it easier. They can put on an airy and light floral skirt combined with a blazer and look and feel just fine in the office. And a white blouse with trousers can create the perfect look for a female manager.

There are a few points to remember: Never wear anything sleeveless and never wear anything with spaghetti straps. These rules are the same for all office workers, no matter the industry.

Apart from that, both genders should ensure their body hair is under control. No chest hair should show from a man's open shirt and women should shave their legs and armpits. And office workers, of course, should go to work smelling fresh. (dpa)
