Gown guide
You can purchase either an MA gown or a BA gown. BA is for ages up to 24, MA for ages 24 and over, and if you already have a masters from cambridge or you are doing a PhD, you may as well get an MA as nobody really minds (disclaimer, this isn’t technically the case according to the chart below. But the others are all strangely expensive, for some reason). (Larger image here)
