What you wear for your MBA interview is an important part of your strategy; professional presence and situational awareness contribute to whether or not you will be successful. What you wear for your interview depends on its context.
A more formal on-campus interview, for example, will require you to wear formal business attire. This means for men, wearing a suit and tie, and women, either a pantsuit, skirt suit, or the tried-and-true dress and jacket combo. However, if you meet an alumnus at a coffee shop, dressing down is probably the way to go.
Men should opt for a dress shirt and pants to dress business casual, while women should wear either a dress or a professional top with either pants or a skirt. Whatever you decide to wear, make sure that you don’t show too much skin and keep your accessories (jewelry and footwear) to a minimum. You don’t want what you’re wearing to make a bigger statement than you do.
