DD has had a "uniform" fr several years now. It is just lax enough to be nice:
Shirts must be collared and tucked in (overweight or not). (Or turtlenecks)---any color, stripes, floral, doesn't matter as long as there is a collar.
Shorts no shorter than 2 inches above the knee. Skirts to the knee (at least).
Pants can be jeans, khakis or whatever. Not torn, ripped, holey, etc. Capri length on down. If there are belt loops, there must be a belt. A belt can be leather, a sash or whatever. Pants cannot be sagging. No skin is to show (not short tops).
For our school it is more about modesty and neatness than a true uniform. It is great for the students and great for the parents. I think more school should adapt and enforce this type of code instead of going sooo strict or not enforcing what they do have.
Good luck, Serena!
