Interesting topic!
I have just had this discussion with my husband. I dont know if any of you are aware of the bushfires ravaging southern Australia right now. Well, we had the warnings and got evacuated last week. Totally scary time which I never want to go through ever again.
I had our valuables ( photos, med records, birth certs etc), a change of clothes, formula and bottles for baby, blankets, some toys, some jewellery ( yet I forgot my other Cartier watch) etc packed in the car. I really ummed and ahhed about taking my few Chanel items with me. What I did take were the authenticity cards, swing tags and receipts from the stores.
My bags would be under the general household insurance. I think things will have to change there...
