"Sderot Ha'Me'atzvim" - it's a designers outlet store. They have tons of
dresses of all sorts of different styles. and they can make alterations etc.
It's possible that you might even be able to order a particular dress in a
particular color, but I don't know for sure.
There is a store in the old industrial area of Netanya.
