So, last weekend I went to a birthday party with my son, who is 5 and in Reception. It was for a girl, and was a 'Princess and Pirates' party. There was a couple of very attractive young women there leading party and dressed as Disney princesses; one was Belle.
I was rather bemused by the American accent they put on (Belle doesn't even have one in the most recent film!) and with the encouragement of the girls to 'act like a princess' which entailed learning to curtsy, and swish their skirts to look pretty. They did a nice dance which 'the boys won't want to do'. When the kids got a little excited about the dancing, 'Belle' asked them to calm as it was supposed to be a 'nice dance'.
In fairness some of the girls liked it, including the birthday girl, and that was the main thing, but I just hated how the girls were encouraged to show just how pretty they were. AIBU to think this is casual sexism? (I think I am probably overthinking it really!!)
