A fifth year pupil, who is behind the campaign, hopes the school will relax the strict rule, which has seen children wearing blazers on some of the hottest days of the year.
He claims that in the most extreme cases some pupils have to receive permission from teachers to remove them whilst inside the classroom.
The petition has already gathered over 135 signatures in the first week of the new term.
Scott said: “I set it up on Monday morning, because they became stricter about enforcing blazers even in hot weather.
“They were brought in in the summer of 2015 after some students voted for them in a poll.
“We want them changed because we did not know they would be mandatory.
“They are ugly and they are not worn unless forced, so they are obviously unpopular.”
He added: “They are also too expensive for how they appear. They cost £30, which is not bad but it is not great for the appearance and they are uncomfortable.”
However, Scott does not want the blazers to be abandoned completely, instead he wants pupils to have the choice.
And he said: “We just want them optional so those who enjoy wearing a blazer can and those who would rather just wear a shirt can.”
Dumfries and Galloway Council were approached for a comment.
