Justin Wright wants his Arizona middle school to do the right thing by letting students choose their own school clothes.

The (Yuma) Sun reported online Saturday that 14-year-old Justin has collected 250 signatures from fellow students at Centennial Middle School to repeal the dress code.

He says the policy violates students' free speech rights and costs families more money to buy special clothing for school.

Crane school district spokesman Chris Weigel says students' rights aren't being infringed upon and research shows uniforms are less expensive than street clothes.

The school requires students to wear solid navy, red or white shirts and bottoms in khaki, navy or denim. Flip flops, high-heeled shoes or shoes with wheels on the bottom are banned.
