At Christmas dinner my FI's cousin asked if it was ok to wear jeans to our wedding since it's winter time and will be cold. WTF?! Never mind the fact that our reception is at a historical monument/museum. I could not help but be offended. I personally think she did it as a jab since she doesn't like that we are having a "small" (150 people) wedding compared to hers (350 people) and hers was a big hotel ballroom affair.
