To think it is very bad manners of my sister to wear a hat to the table on christmas day?

Were going out for a meal as the whole family on christmas day as there will be 10 of us and no one has the space to entertain everyone.
My sister has had a few issues with her hair and as a consiquence it was cut very short. It has not grown back much since the incident so to compensate this she wear hair extensions. Problem is she doesnt do them very well and they look a mess. She cant get them sorted before xmas and is now insisting she is wearing a hat to the table, similar to this one. I think it is really rude to do this especially as we will be out in a resteraunt but she is now say that Im trying to humiliate her.

If I were you I'd just try and keep the peace.
Say to your sister that you don't care if she wears a hat or not, but that your Grandparents will possibly find it rude, because that's the ay things were in their day. But you'll help her by explaining to your GPs that she has had a problem with her hair extensions and feels terribly embarrassed.
