Each school has 2 color polos + white polos that they can wear. This year the school district closed a couple schools and so those students will be going to other schools. They are going to allow those students to wear their old polos for this year only. After that, they will be required to wear the proper polos for their new school.
They went with "uniforms" because the dress code was not working. There were guys who would still wear their pants below their butt, with a long shirt over it.
but rules are rules 
"Knee length" is easier to enforce than "within 2"" etc. - if it's sitting on your knee, it's good, if it's not, it's not uniform and needs to be replaced with uniform.
