Q: I've been out of the work force for a while. What should I wear on a job interview?

A: Interview dressing basics haven't changed much. Rule one: You only have one chance to make a first impression. And your clothes, makeup and hair are what a potential employer notices first. But exactly how do you pull off a look that is modern, confident and competent? For starters, wear something you're comfortable in, because if you don't "people will sense your insecurity," says J.Crew design director Tom Mora.

Whether you are interviewing at an art gallery or a hedge fund, one fundamental rule applies -- it is better to be overdressed than under dressed. A modern, tailored blazer with fitted trousers or a knee-length skirt is always a smart option. The trick is to put a subtle, stylish, personal stamp on the look.

"A lot of women think that wearing a really bright color top under a dark suit livens it up, but more often than not, especially with a black suit, it can look cheap," says Mora, who recommends wearing a more muted colored top -- such as melon or blue-gray -- with fashiony details for a modern, personal-style touch. "A top with a beautiful detail [like draping] at the neck or down the front can give a serious suit a more feminine look."
