You shouldn’t wear colorful cloth while giving interview. White shirt and black pant is more effective for this. Don’t wear cloth with big and bold print the person who takes interview might not like this. It is good to wear brown belt and black shoe as this will show you more classy.
Don’t wear such clothes which is very tight. This will make you feel uncomfortable and there might be wrong impression to the interviewer. Jeans is considered as casual dress and this is not good in interview. Wearing grunze pant will leave the wrong impression.
