Remember that looking good will make you feel assured.

Well-fitted clothing projects' confidence that you want the interviewer to know.

Make sure you wear something that fits the company's image you are applying.

Make your clothes neat and clean. It's a symbol of being organized.

Dress in a manner that you'll be able to maintain if you get the job.

Bring along a leather briefcase or a trim handbag (to free hands for handshaking) which must be in good condition.

Overdoing your hair (and makeup for ladies) will make the interviewer think you take long break and stay in the restroom longer than usual.

Open buttons (Too short skirt for ladies) will send a wrong signal of being flirted and will make the interviewer think you're dangerous to anyone's concentration. Being conservative is your best bet. Close-toe shoes do not only look conservative and appropriate. It is also safe for your feet at work.
