Once we were invited to an elders house or a get together and we dressed casually I wore a tshirt and trousers. I later found out the Elders wife had expected everyone to wear meeting clothes and she was appalled at my choice of outfit. What was worse she told everyone how badly dressed I had been without actually speaking to me about it. I wouldn't have minded if there had been a suggested dress code in the invite. It is such a petty thing to b fixated on.
Since leaving and purging my wardrobe I have discovered I don't like wearing meeting clothes and I wear T shirt and trousers a lot.
