it is : dress up
dressing in formals will give a good impression , also it is a confidence booster
A good rule of thumb is to dress one step above whatever the typical work entire is for the position you’re interviewing for .
If employees wear uniforms at the job, wear smart casual (jeans, blazers, blouses or neutral t-shirts)
If employees wear smart casual, wear business casual (trousers, dresses, button-down shirts, sweaters)
If employees wear business casual, wear business professional (suits and ties, pantsuits, long skirts, heels or loafers)
Always err on the side of overdressed..
