When I was a child I was forced to wear nylon raincoats all the time and like you I was bullied.
Once married this returned and now ex loved it. I wore a raincoat at all times outside unless weather forecast said 0% raincoat but still had to take my mac with me.

Re: being forced to wear a old rukka raincoat
Another one here made to wear a nylon pakamac as a child throughout my teenage years. And always buttoned to the neck too. This was in early 1980s
