Packing Euro 17

Yes one of us is packed but you are not really sure until both suitcases are zipped up but there is still a few hours to go.  Mine comes in at 23kg. The carry on is good at 3.5kg.  I am taking an extra camera and a new coat which together must be 3kg.  There are three formal dining evenings where coats, collars and ties are mandatory. For the first time I have got this properly covered.  A few years back there were French chateaux we stayed at where dress codes were high and we are using chateaux again. I have been consulting my packing checklist which has around 150 items all up.
