Advice please.
My 13 year old DD is 6' tall . Her school uniform is a navy pleated skirt with a flat panel first from waistband and then pleats from below hip level. She hates the panel so rolls the skirt over at the top. This puts it as several inches above the knee. I ask her daily to unroll it, school ask her most days to sort it out. School rang DH this week to say they would escalate the issue if she kept disobeying. I have removed her phone and said she will not get it back until she conforms. She sys everyone else does it and you get teased and bullied if you don't. I suspect hers is more obvious as she is so tall so far too much thigh showing. Apart from this she is being fairly well behaved. When I got home today from work she had cooked us all tea,walked the dog and got the washing in. I gave her a big hug and said thanks and then noticed the wretched skirt hoiked up. It is making such a bad atmosphere and I really feel at a loss as to how to explain to her that she just has to follow school rules. Any ideas?
