Anyone know of an orchid to match this description?

[The Orchid Boy]

I have a relative who wants an orchid but they want it to be a "perfect" orchid.
These are the requirements...
-HAS to be quite large and bushy so that it looks like a regular foliage houseplant when out of bloom
-They would like it to be the color "orchid" or like a light purple or lavendar color but this is not absolutely necessary

This is the growing conditions in their house: They have a large east facing window that gets pretty sunny, they also have very few smaller windows.

Any recommendations??? I was thinking some kind of cymbidium...
