Your wallpaper might be the best feature for your dressing room and just let it show right through a clear acrylic dressing table.Or you could continue with your touches of gold on a new vanity or by using a bit of gold leaf on an antique one. Add a gold chair to a rosewood vanity to continue with your bedroom look. My personal favorite is #4 ,5 & 6 below. Love the curves and a desk will work too.

Paint is a very inexpensive way to change a room. If you really don't like it I suggest paint, it will make the biggest impact.

Thanks a lot for your comment. I wouldn't exactly call it a walk in-closet. As you can see from the drawing, Its space provided for two single wardrobe (one on each side). Maximum width can be around 3.5 ft. The humidity point is quite relevant. The question is would it be possible to include a wet room in the space i.e. 6ft x 8.6ft. - considering I don't remove the dress wall. Wanted to get a sense on the possible layout. Thanks and look forward to your advise.
