The growing professionalism in offices and boardrooms, the expectation in terms of dressing too has changed a lot. Employees are expected to dress in sleek business suits and formals to maintain the decorum of a thoroughly professional environment. In this case men have a very limited choice with shirts, blazers and trousers but women have a comparatively wider range of options with skirts, slacks, formal dresses etc.
One thing to remember with office wear is that it should never be over the top. Try to go for subtle colors, smart cuts and decent stitching. Blazers or trousers should be well fitted while skirts should not be too short. It is advised to dress as simply as possible and stick to the basics until one gets a knack for the respective workplace.
