London, Nov 10 A Brazilian college, which expelled a woman for wearing a short, pink dress to class, has had to reverse its order after it received negative reactions for the move.

The private Bandeirante University had to take back Geisy Arruda, 20, after the Brazilian government sought an explanation from the university.

The Education Ministry had given the university 10 days to clarify its reasoning for kicking out Arruda, who had to put on a professor's white coat and was escorted away by police amid a hail of insults and curses from other students.

A video of the incident was posted on YouTube and quickly made headlines across Brazil.

The university's decision to expel the student prompted complaints from the national student union and the country's minister in charge of women's policy, among others.

Arruda told reporters through her lawyer that she was going to sue the teaching institution and hopes she could finish the semester there.

The dean's note gave no reasons for why the decision was being overturned.

Although Brazil is known for revealing clothing, especially in beach cities, where many bikinis are referred to locally as "dental floss", most college students dress more modestly on campus, commonly in jeans and T-shirts.

The university published newspaper advertisements saying it expelled Arruda for disrespecting "ethical principles, academic dignity and morality".

The adverts also alleged Arruda acted in a provocative manner incompatible with the university environment, and university lawyer Decio Lencioni told Globo TV that the institution was only following its rules.

"The problem is not her clothes; it's her behaviour, her attitude," the Telegraph quoted him as saying.

Lencioni and the university said Arruda even raised her dress and stopped to pose for photos the night she wore the short dress on campus.

He said she also chose the longest way to get to class to attract the attention of more students. (ANI)
