When in doubt, it is better to be too conservative than to be too flashy. The key is to look and be professional. For men and women, a suit is the best bet. MEN A dark two-piece suit is the most professional. Solid colors and tighter-woven fabrics are safer than bold prints or patterns.
Bright ties bring focus to the face, but a simple pattern is best for an interview.
Make sure your shirt is clean and crisp. Wear polished shoes with dark socks high enough so no skin is visible when you sit down and cross your legs. A solid dark suit with a knee-length skirt and a tailored blouse is most professional. Accessories should be kept simple. Basic pumps and modest jewelry and makeup help to present a professional look.
