Seriously not to offend anybody, Kate cant be considered as 'classy', she is a very 'normal' girl. Dellals family may belong to the London's high society but not for other communities or countries. They stand as a family not as an individual figure except Alice Dellal who is a top model. But I agree that Charlotte may have courage to come to London because her connection with Alex. They did say she is an independent lady but without any social circle that she trust, I dont think she would make the first move (to be based in London)...
