I recently helped a friend install an art exhibit in a gorgeous historic mansion just outside of DC, and it had a room very much like this. It's the "bride's room," used for dressing of the bridal party when weddings are held at the mansion. I think your dressing room is absolutely fabulous, and you deserve it! That rug is beautiful too.
I really like my closet even though it is nowhere near this size. Since we had custom shelves and racks installed a couple of years ago, it's so much easier to use. It's a narrow enough space that it's hard to photograph, even with a wide angle, but I keep trying. My husband even likes that I have a wall of shoes in it!
