I know a few local stores that make antique reproductions which is what that picture looks like. You can also go to antique malls buy something older and paint it white. You have many possibilites. I would also try ebay and Amazon.
Visit a few antique shops/used furniture barns. It's called a dressing vanity, or dressing table. Try Craig's list.

I went on a site on this topic but can't remember the name, If I'll remember I will let you know.
Anywhere they sell furniture. eBay, Google Shopping, Amazon if you are shopping online.
