My suggestions:
A better wig, possibly one with bangs to cover your forehead and maybe shoulder length as well.
As has been suggested, jewelry. A necklace, earrings and bracelets.
Hip and butt padding to give that "hourglass" figure.
Slacks or a longer skirt. Yes, it's fun to wear a mini skirt, but that's for the very young. Most women your (apparent) age would chose something knee length or longer.
Have fun!
