Not every school asks for a photo. Some secondary applications do, and so do some interview platforms and student profiles. Read the instructions for each one. If a school gives a size or file type, follow it.
A good application headshot is simple: your face and shoulders, a calm background, and a photo that looks like you on interview day. A Charcoal Suit is the safe pick while you apply. Save the White Ceremony Coat for after you start school. For the background, a plain studio color such as Clean Gray or Light Blue is a safe choice.
