Cowboys and Indians outfits have been banned from fancy dress parties by snowflake university students.
Mexican-style sombreros have also fallen foul of the politically-correct rules, which student leaders say threatens peoples safe space.
Among the other costume ideas hit by the edict are dressing up as chavs, priests and nuns or IS bombers.
However, the fancy dress guidelines approve of doctors and nurses, Ancient Greeks, Romans, cave people and aliens.

The sniffy commandment was made by the student union at the University of Kent, which claims to speak for 20,000 students at the campus in Canterbury.
It says dressing up as a particular race, culture or stereotype is offensive and will not be tolerated.
But the proposals were ridiculed yesterday. Rob Lyndhurst, a 33-year-old father of two from Canterbury, said: To think these people are supposed to be among the brightest young people in Britain.
Ive got two young boys and they love to play cowboys and Indians, just like I did when I was a lad.

Im not a racist, I just like to have a laugh and crack a joke. And if someone tells me I cant dance because Im white, or I like little boys because Im Catholic, I certainly dont take offence, I just laugh because its a JOKE.

I wonder where exactly these safe places are? Locked in their bedrooms hiding under their covers? The union said: 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 individuals race, gender, disability or sexual orientation or based on stereotypes.
Also banned by the union are dressing up as celebrities known for their sexual misconduct or abuse of power such as Harvey Weinstein or Jimmy Savile.
Outfits with historical or religious themes including Crusaders, Israeli soldiers, IS bombers and the Prophet Mohammed.
The union added: Fancy Dress themes should also not be centred around political group stereotypes or the stereotypes of different levels of perceived class in the means to diminish their worth or validity.
Recently it accused the Tokyo Tea Rooms in Canterbury of cultural appropriation after the bar used white women dressed as geisha girls to promote its opening night.
Matt Goodwin, of Kent Union, said the fancy dress policy was a draft proposal, adding: We will be consulting with our executive groups to gain further feedback.
