I'm sitting on a bench as my son is asleep in the pram, just observing the fashion of young-uns (20 and under).
80% of those who have passed me are wearing large grey jogging bottoms, a small tight vest, long straight hair and... Crocs with socks on! Oh and minimal make up.
It's so different to what I wore in my teen years!
Is this the fashion where you are? - for reference I'm in North London.
