Business Dress
In business, Finns dress conservatively, usually dark business suits in the winter and light suits in the summer for both men and women.

Dress codes depend very much on the industry and workplace traditions though they have relaxed substantially over the years. Men typically wear suits or jacket and shirt, often leaving the tie out. Jeans or chinos have become very popular too. Women dress basically like other western women in the workplace.
Dressing for social functions is casual unless it is specially mentioned in the invitation.
