When I first read your post I just knew they were going to look like that before I saw the picture!
I wore these when I went to college as an 18 year old in 1978. I wore them with neon socks, a multi coloured striped cotton grandad style long shirt with a hessian look gathered skirt and wide belt over. It was ironic fashion at the time. 'School' sandals, which these were, basically, were deeply unfashionable, so I made them stylish. It worked at the time! I didn't have the money to buy the latest fashions so I wore anti-fashion.
I do NOT suggest you style them like I did!
