Chotiros, also known as Amy, will be rebuked for wearing a revealing, "sexy" outfit to the awards, Thailand's version of the Oscars.

The event was held at Nakhon Ratchasima and attire worn by Chotiros has caused a stir and thrust her into the limelight. She has attracted criticism because she is a liberal arts student at the leading university.

Rumours that Thammasat bosses would ban her from July's graduation ceremonies were denied by her faculty dean Sithichoke Waranusantikule, who said the school had no power to punish Chotiros.

"However, I can say I am uneasy with it," he said.

The incident was raised at yesterday's universities' executives meeting and it agreed the student should be admonished for "inappropriate behaviour".

Thammasat rector Suraphol Nitikraipot said its students should be responsible not only to themselves but to the school and society, too.

"Society feels this is a disgrace and her actions have affected the reputation of this university.

"So, we will ask Chotiros her reasons. Any punishment will depend on her explanation," Suraphol said.

Sithichoke said Chotiros studied well during some terms but poorly in others. She never dressed inappropriately when attending university.

"I am concerned the university has been involved. I have many students who become stars but never face these problems. But, the university will give her a chance," he said.

Chotiros attended a class yesterday and said she had not been reprimanded and had been told she could be absent if she felt uneasy.

"It's impossible the university would take this matter so seriously," she said, adding she had yet to receive an official approach from the school. "I have no idea what people feel about my dress. I didn't wear what I wore to make me famous. I'm like any other actress who uses sex appeal as a selling point.

"It's the trend - sexy fever," she said.
