Aveline
It it highly likely that others will be laughing at her behind her back. Not kind. Not kind either to patronisingly praise her sartorial choices.
That's a good point Aveline.
I've seen it. I've also experienced it.
I was in Vienna, it was winter, and I was wearing black velvet shorts with a sweater. The shorts were most definitely not short; I wore them with thick black tights and flat shoes. In the UK, no-one would have given me a second glance, but in culturally conservative Austria, I garnered some disdainful looks. I was peering into a shop window and could see behind me two women - around my age then (early 50s) sniggering at me. It was very uncomfortable and I never wore the outfit again, even though I thought it was a very sober one. Silly me for not observing the 'when in Rome... advice. My OH told me to ignore, said I looked "great", but it's really not nice to be mocked, and I'd want to protect a friend from experiencing that.
