The way you look may not make up for poor performance, but it could give you a competitive edge during your interview and in your future career. Employers often decide whether an applicant will fit in with their organization based on a first impression. Your image is a statement of who you are and what you represent, and it will help you get the job offer. You only get one chance to make a first impression. There are no specific rules regarding attire.
Appropriate dress differs based on the occupation, location, and preference.
However, no matter the circumstance, dress as well as you can for the interview. Dress found in the work world is quite different from dress found on campus, and if you are in doubt, it is always better to dress up for the interview. You should be prepared to spend more money on interview clothing, but the added costs will guarantee you quality material and a good fit. Most large department stores have Personal Shoppers on staff. These fashion consultants will work within your budget to help you coordinate a work wardrobe for your style and industry.
