those huuuuuuuuuuuuuuge heels

I've only seen her in baby daddy.
I think it's the first time ever that I notice the shoes of a sitcom protagonist.
No idea what Aniston or Cuoco was wearing
But the heels she is wearing are bigger than her! :P
She is so tiny, on those stripper heels, I feel like she will colapse or something
Why wear those?
Is she insecure with her height ?
