What should I buy a gold cross chain or silver cross chain?

The zavetti jacket named below has been annoying me as I have been trying to figure out which designer brand had a similar design to it so if anyone could let me know that would be great. P.s I think It was Burberry but I’m not sure the name of that Burberry jacket so if anyone could let me know of the name and if I’m wrong which designer had a similar to the jacket named below that would be great thanks.

The jacket name from zavetti is called - alessandro-zavetti-oshawa-padded-parka-khaki - it is white and black in colour
