Grooming for Interview
Proper Attire for Men
For most interviews, men should wear a suit and tie. The most common interview suit colors are navy blue, gray or a subtle pinstripe. Brown suits are also acceptable, although black suits are often too formal and dressy. Leather lace-up or slip-on shoes with socks that coordinate with the color of the suit are a must -- no gym shoes or white athletic socks. The tie should be silk, either solid color or a subtle pattern; no knit ties. Belt and shoes should match or closely coordinate. Jewelry should be kept to a minimum, although a class ring or wedding ring and a watch are fine.
Proper Attire for Women
Women have somewhat more latitude in color than men, although it's preferable to stick with conservative shades and patterns. A dress and jacket, a skirt and jacket or a skirted suit are all appropriate interview attire for women. Pants suits are also usually acceptable for all but the most conservative companies. Skipping hose is OK, but open-toed shoes usually are not. Shoes should be flat or have a modest heel. A single necklace, earrings, watch and one or two rings are sufficient to add a finishing touch to your outfit. Necklines and hemlines should be modest; save short skirts and skimpy tops for the club.
Blue-Collar Job Interviews
For most interviews for blue-collar jobs, a suit and tie are fine for men, and a skirted suit or pants suit are completely acceptable for women. However, for very informal interviews, wearing a formal interview suit could be out of place. In such instances, a jacket and button-down shirt with or with or without a tie along with pressed slacks make a good suit alternative for men. Women can wear a somewhat more casual dress or skirt with a button-down blouse or top.
Grooming and Hygiene
For both men and women, clean, neatly styled hair is a must. Men may wear neatly-trimmed facial hair, although some conservative employers frown upon it. Men with long hair should consider getting a shorter cut -- at least until they receive a job offer. Light makeup is fine for women; but both men and women should go easy on the cologne. Cover visible body art and remove piercings, including earrings, for the interview, although a single pair of earrings is acceptable for women.
