DD is starting year 11
She did a big 'grow' over the winter & at Easter I bought her 2 new skirts - totally in line with the school's policy on school uniform. With the intent that they would last her until the end of year 11
In May the school announced a new school skirt; same length as current rules but a new 'style' & it MUST be worn
I don't want to buy 2 new skirts as I have 2 perfectly acceptable ones that fit & are the right length
Am I being unreasonable to be decidedly miffed?
