Student leaders at a Ugandan university have asked their classmates to stop wearing mini-skirts and tight trousers.
The Mbarara University of Science and Technology, in the south-west of the country, has no formal dress code.
But outraged students have voted for women to ditch figure-hugging clothes in favour of long tops and skirts, leading to "drastic" changes.
"Students used to dress in trousers where you could see their g-string," student leader Jeff Rwakamuna said.
"They would wear short things and tops that are up beyond their belly buttons.
"If you want to dress like that for going to a club to dance, or to a bar, fine, it's OK to dress that way," he told BBC News Online.
"If you are a student, dressing like that sends a wrong signal - you have to reflect the status of the university," he added.
Lecturers were also being distracted by scantily dressed students in the front row, he said.
"The need for decent dress has been expressed for some time," the dean of students Emmanuel Kyagaba told BBC News Online.
"Our ethical requirements involve all our students to dress as required by some of the professions they will engage in," he said.
Women are now asked to wear dresses and skirts that fall just below the knee.
Trousers should be loose and tops should cover the stomach and belt.
Any inappropriately dressed students are taken aside and asked to "dress like you are going to lectures".
The move has been a great success, Mr Rwakamuna said.
"People are calling me and saying it is good, and the lecturers are organising an award for me," he added.
