The standard job interviewing attire for women is a conservative dark navy or gray skirted wool blend suit. Job experts and employers seem split on the notion of pants suits, so a skirted suit is a safer choice.

Other conservative colors -- such as beige or brown -- are also acceptable. Red is a power color. A blazer with blouse and skirt is a possible second choice to a suit. You should always wear a jacket.
Skirt length should be a little below the knee and never shorter than above the knee -- no night club attire here. Avoid wearing a dress (unless accented with a jacket). Blouses should be cotton or silk and should be white, or some other light color. Shoes should be low-heeled.
Make-up should be minimal, with lipstick and nail polish conservative tones. Pantyhose should be flawless (no runs) and conservative in color. Do not have excessive body odor or cologne.
You should opt for a briefcase rather than a purse.
