This is supposed to be your opinion, but I would say no.
Possible reasons for no: They can't express themselves, Some may not have enough money to pay for uniforms, Some may be uncomfortable wearing that type of clothing that is necessary.
Possible reasons for yes: They know what to expect/don't have to worry about what to wear, It's more formal and can earn the school money, etc.
Sorry but I lost my glasses and can’t see that sorry
