Thanks for that, if it was before 1944 then at least we can narrow it down a little.
The Jewish connection comes mainly from the photographer used. He does appear to photograph mainly Jewish weddings, and of course the OP said Eva was Jewish.
It is just a better scan we need plus information on Eva's age etc to help us along.
I agree about the dress, I suspect in close knit communities like London Jews wedding dresses were passed around at that time and I would guess it was originally a pre war dress.
