I have to go to a conference tomorrow. We (as in my boss and I) think it will be casual as it's an agricultural conference, so jeans and a collared shirt for the men but probably no ties. Neither of us have ever been before and it's only me going.
I'm planning to wear my smart jeans and a shirt (with collar) and a blazer. I will need to wear something else though as I'm always cold. Would a cardigan look weird under a blazer (too many buttons)? Or should I rather wear a jumper?
