More than likely she just has no taste.
I have a sister-in-law like that. She's almost 40 but dresses like she is 18, a ty 18. She uses the fake-n-bake tanning bed every day to the point that her skin is now looking leathery. She's had her lips done, her boobs done, her teeth done, had the permanent makeup tatoos, her hair is dyed jet black. She lives in the gym, and should look good, but actually just looks odd. When she was 22 she was pretty attractive, but has tried so hard to hold onto her youth that now she is just getting a little scary looking. The sad part is that she has spent tens of thousands of dollars creating this image of hers. I call it the Michael Jackson Effect.
My sister-in-law is not a hooker, but she could play one on TV.
