Are student dress codes really needed?

Yes.

The dress codes, or uniforms in some schools (particularly European and Asian schools) are vital to helping in promoting the image of the educational institution. The better the institution looks, the more students the school gains. Therefore the more money they earn to buy better resources in order to be able to provide better education to students.

Uniforms or dress codes in schools are also preparing young people for the world of work, where uniforms or dress codes are a way of adult life.

Uniforms in schools also promote equality between students and lessens bullying in schools which is normally student differences, because the uniforms eliminate the differences by giving everyone the same image.

While many people agree with the reasons, above, for instituting dress codes in schools, there are also many people who do not consider those reasons to be valid, or important enough to justify further regimenting the students.
