Interviews do fail but you can stop failure for the rationale of not looking pro enough when going for that vitally important job. Your clothing is one the 1st things the interviewer will spot about you when you walk into that room. So , it is important to select the proper and acceptable clothing for the job that you are going for. Here is a few tips :

For an office job or professional job, go for suits, i.e. Trousers / skirts, shirts, jackets and smart shoes. Do not forget ties for the gentlemen. Wear white button-down shirts / blouses, long or knee length skirts for the ladies and black smart shoes for both men and women.

It is unimportant if this is not your common dress style. If this is the job you need then you need to become used to the idea of feeling and looking smart. Women keep make-up as small as possible, hair fresh and clean for both women and men.

For the more casual job i.e. Retail work, restaurant etc . Dress in a smart but casual way. Make sure you are coordinated and smart. Ladies can wear skirts or trousers. No jeans and no trainers. Wear nominal jewelry and make-up.
