I asked my kids whom have been in both polo shirts and ties
school 1 polo and sweatshirts
scool 2 sweat shirts shirts and ties
School 3 blazer shirt and tie
school 4 Shirt tie and Sweatshirt
School 5 no uniform (in Denmark)
school 6 (secondary) shirt and sweatshirt
(I have 4 kids and none of them have gone to all 6 schools)
so
dd1 (school 1 2 3 and 6) says she likes her present uniform the best shirts and sweatshirt but wishes they didnt have to have sweatshirt in the summer)
dd2 (school 1, 2, 4 and 5) prefeered no uniform at all but if pushed she prefeers her current school (shirt tie and sweatshirt)
ds (school 3 and 4) prefeered school 3 shirts ties and blazer says the sweatshirts gets to hot and uncomfortable he likes summer in school 4 (current school) whre they are allowed short sleeved check shirts and no sweatshirt.. (good thing as when he goes to 2ndary he will end up in blazer and tie laughs)
dd3 has only tried school 4 so has no clue about preference.
when asked about the polo shirts they all said they got stiff and itchy and didnt feel very comfortable in the summer
so much for them being better for kids.
Personally I prefeered school 3 with the tie blazer and shirts as I think they looked smart
now as for if the school can do this yes they can but from what I know they have to make it known to parents whom can then object/voice their concerns. My friends childrens school did this and thei intention was to have a summer dress for girls that was a white chest piece and then check for the rest the parents were in uproar (nice with tomato sauce isnt it laughs) and it got changed to just a plain usual check dress.
dd2 will in September (providing we get school of choice but feeder school and only one in catchment area so changes are high) will end up in cardigan shirt and tie so will be a 7th option for us
