An office suit (with trousers or a skirt) should be made in a calm color scheme.
The most acceptable styles of skirts are straight, flared and pleated. Their optimal length is knee-length or slightly lower, and the colors are black, grey, brown or dark blue.
Blouses or shirts should not have revealing necklines. Light colors are better: white, lilac, peach, blue.
Inconspicuous plain dresses with long sleeves and covered shoulders without bright details are appropriate to wear in the office.
A mandatory element of the dress code is tights or stockings in nude, gray or black colors. Bare legs are a taboo for office style at any time of the year.
The dress code requires closed, elegant shoes only. Its cost is not important, but if we are talking about a high position, then it would be quite appropriate to use luxury shoes.
