Your IT services company designs and installs networks for Fortune 500 clients. As the lead IT network engineer, you are having a meeting with the CIO of a large accounting firm. What is the most suitable attire for your position and interactions with clients?

You should dress in business formal attire if you're in a lead role and have meetings with clients in larger companies. This would include a matching suit coat, pants, or skirt, and a tie if appropriate. Many techs dress in casual khaki pants and polo shirt, but this is not the attire you would choose to impress a potential new client.
