Here, sweetie, here is the place for you. It's in the Woodland-Normanstone neighborhood, which is the most expensive neighborhood in DC.
Note the price reduction!

If you were as rich as you are trying to appear, you wouldn't be "driving" yourself "around" anyway. You'd pay someone to do that. You wouldn't care where the stores were, because your staff would do the shopping for you. The boutiques would present private trunk shows in the home for you and a few high wealth friends.
Also, you'd stay in California and let your husband do his work here and fly home to see you once in a while.
