So, I know you all think I'm going to be talking about the overt sexualisation of girls... but actually, I'd like to think that most feminists would agree that's just ridiculous. 
Rather, I'm interested in something I've been noticing recently which I think is more subtle. DS is 2.5 and so at nursery, out with friends, at the park etc I see a lot of similarly aged girls. None are wearing, "I'm too sexy" t-shirts which I guess is a relief but I have noticed a distinct difference between what the boys and the girls wear. Most specifically, they always have something tight on their legs - leggings, jeggings, tights etc. While the boys tend to wear just regular trousers or trackies or whatever.
I noticed the same in the summer - DS and his little friends wore plain shorts, often relatively long sitting somewhere above the knee. The little girls all wore skirts or leggings and if they did wear shorts, there were much shorter (not obscene, but still).
It just felt like girls are being taught that they need to define and emphasise their legs from a very early age, even when supposedly they're wearing "practical" clothing? Or perhaps the problem is that boys aren't being allowed to wear tights/jeggings etc which are perhaps more comfortable?
What do you all think?
