The academic dress prescribed by the University of Bristol is a mixture of that prescribed by Cambridge and Oxford. Bristol has chosen, for graduates, to mainly specify Oxford-style gowns and Cambridge-style hoods. Unlike many British universities, the hood itself is to be "University red", lined with a specified colour. University red is defined to be Pantone 187. Bristol also specifies that undergraduates are to wear gowns "of the approved pattern" in certain circumstances, although the pattern itself is not specified. This is not too important since, in practice, undergraduates are never required to be gowned except when graduating.
