It’s true there are a lot of variables when it comes to appropriate workplace attire. Factors to be considered are the type of work, the industry standards and even the weather.

But Kim Johnson Gross and Jeff Stone, authors of “Dress Smart Men: Wardrobes That Win in the New Workplace” and the companion book “Dress Smart Women” (Warner Books), offer the following guidelines to build a wardrobe that works for you.

When choosing an outfit for a job interview, they suggest the following:

• Avoid fleeting fads. Find a consistent, predominantly classic style that works for your personality, your office environment and the career path you want to take.
• Dress the part. Call Human Resources to find out the dress code. Research the company and show up wearing clothes that reflects its values, ethic and style.
• Shop smart. Pick a new item only if it completes a look or if you already own at least two items that go with it. Don’t buy anything without trying it on first.
• Separate your work clothes from your play clothes and don’t mix the two.
• Reserve the largest chunk of your budget for the suit. Choose one made of a nice fabric, with clean lines, and in a neutral color that will easily mix with other wardrobe items.
• Try on your whole interview outfit a week before your interview to make sure everything fits properly and matches accordingly.
