I have to go to an interview to get into a well-know NY culinary school, and I want to make a good impression, but typical "business wear" is obviously out of the question. Soon I will also be starting a personal chef business, and I'll need to meet with potential clients to plan menus etc. Again I will need to look professional but not show up in a matching pantsuit, so what are the main things I need to keep in mind when I need to "dress to impress"?
