How people dress greatly affects the outcome of their job interviews. But what you should wear varies with the type of work you're seeking. Here are some tips you can share with job seekers you know.

Generally:

1. If the job is at a factory, wear a dress shirt and slacks.

2. If the job is for a nonmanagerial position, men should wear a shirt and tie. Women should dress at that level.

3. If the job is for a managerial position, men should wear a suit and women should dress at that level.

But exceptions do exist. For example:

1. If the job is at a Silicon Valley software firm, you will look like you already work there if you leave the coat and tie at home.

2. If the job is at an IRS office, you will look like you already work there if you wear a "Sick Bastard" t-shirt.
