According to "Dressing for Success: How to Dress for an Interview" on About.com's Careers page, job candidates who wear jeans, sweat suits, rumpled clothes, short skirts, or sneakers; show pierced body parts or tattoos; wear their hair spiked or unnaturally colored; or chew gum rarely find success in the job market. Their appearance costs them the job. Like it or not, how you dress really does have the power to make or break a job interview.
