I have DTs aged 4, who have just started at a new school 3 days ago. Part of the uniform is a white baseball hat which they have to wear all year round if they want to play outside (we live in Hong Kong so it is a necessary rule out here as the sun is very strong). The hats are clearly named with each DTs name on the inside lable. Today, both hats came home with each DTs name written in thick black magic marker in inch high letters right across the peak of the hat! On one of them all the letters have bled so it looks all fuzzy and is hard to read anyway. I am really pi**ed off! Not only have they labelled our kids for all to see, (which makes them stand out even more as if being a twin did not draw enough attention to them), they have made the hats look really ugly and odd, not to mention the fact that they have damaged our property. The hats were bought new 3 days ago and cost the best part of a tenner each. No other children have their names written like this on their hats. My DT are not identical, and are really quite easy to tell apart, so I feel this was an unnecessary step, and I also feel the school should make a bit more of an effort to learn which DT is which, rather than (literally) labelling them. If they had asked me first, I probably would have thought about it, and said no, or at the very most, written their names in small letters along the side of the peak, rather than emblazoned in magic marker across the front! GRRRRRRR, am so annoyed! 
I am tempted to ask the school to replace the hats, but is that being a bit too over the top about it? We've only been at the school for a few days, and I really want to get to be part of the wider school community and don't want to become labelled as the nutty lady who complained about somthing not worth getting het up about who should therefore be avoided at all costs. So, AIBU or am I justified in asking for replacement hats?
