I did it a few years ago in DTD, and it was pretty cool. I can't remember the name of the package, but the one I got included a hair style (with color of choice tiara and I think a barette, too) makeup with facial jewel (you get to keep the palette for touchups and sanitary reasons, lol) and a sash. I think that was all. I had a blast doing it, and would definitely do it again. I don't think there are adult costumes, though.
I hope your DW enjoys her makeover!
