Students in Kent have been banned from wearing a host of Halloween costumes including cowboys or sombreros.
The students' union has insisted a number of outfits are ''offensive'', ranging from chavs and Jimmy Saville to nuns and nazis.
In a statement, the union said: ''Dressing up as a particular race, culture or stereotype is offensive and Kent Union will not tolerate behaviours which seek to.''
Also included on the list are priests, Native Americans, Isis bombers, Israeli soldiers, ''Tory boys'' and ''The Prophet Mohammed (peace be upon him)''.
Themes like the Crusades feature - as does the idea of dressing up as a gender or sexuality they don't identify with where ''the purpose is to belittle''.
The union added: ''We empower students to be creative, whilst also ensuring all students feel welcome and safe.
''Students groups are free to engage in fancy dress whilst ensuring they abide by the Fancy Dress Guidelines which include being offensive, discriminatory and prejudice to an individual's race, gender, disability or sexual orientation or based on stereotypes.''
