As a general rule, interview wear consists of conservative attire such as a dress suit with tie for men, and a dress suit with slacks or skirt for women. Choose conservative colors such as black, navy or dark grey, and skip patterns in favor of solid colors. White is a good color choice for a shirt or blouse, or choose a solid color top that coordinates with the suit.
Accessories such as ties, shoes and socks must also adhere to the same rules of conservative solid colors without flashy patterns. Choose not to wear any jewelry, or keep it minimal. For instance, a man may wear a watch or one ring. A woman may wear a small pair of classy stud earrings that do not distract from her attire. It is also important to make sure clothes fit comfortably and are not too tight, small or large for the figure.
When interviewing for a job at a workplace that has a casual dress code, it is still wise to wear conservative attire to the interview. Wearing a dress suit shows potential employers that the applicant is respectful of the employer and position. Depending on the employer dress code, it may be acceptable to wear business casual attire for a second interview. An example of business casual is khaki slacks paired with a sweater.
