You'd be amazed at what a google image search for trophy wife brings up.
<---This is the best I could come up with.

Forget the job search, my new life goal is to be a trophy wife.

All I'm saying is that I've got all the qualifications and more. Sure, I won't be throwing garden parties for the junior league, but I promise to be vacuous and vacant in exchange for satellite tv for Badger and Packer game and being allowed to attend the sporting events you usually only take your clients too. I even promise to like whatever team you want, as long as they aren't in the Big Ten and aren't the Minnesota Vikings or Chicago Bears. I'll learn players. I'll learn history. Hey, I did it for fun with LSU when I moved to Louisiana, I'll definitely do it for you.

Imagine my versatility. Instead of just showing me off to your clients, I'll be talking box scores with them! You can hold meetings and I'll take the other clients to a baseball game. And you don't even have to spring for the boob job.

Why didn't I think of this before?

The wikipedia definition is fairly entertaining, as well as the "Examples in fiction:"

*Loretta Tortelli marrying Nick Tortelli (ex-husband of Carla Tortelli) in Cheers
