Not me
but 10 year old DD.
She has been given a bag of hand me downs which included a Christmas jumper. She LOOVES it and has put it on every day after school.
DH says fair enough round the house but not out and about (we have a rule no dressing-up clothes outside the house) as it isn't even close to Christmas yet.
I think warm jumper, why shouldn't she wear it, it's not the same as dressing up (though admittedly it is v Christmassy).
Who is BU?
