Eh, that's subjective, and even if one thinks she is gorgeous, that doesn't automatically make her a fashion expert.
Just because she's been paid to wear clothes and be photographed wearing them doesn't necessarily mean she knows anything about what she was wearing, and certainly not about concepts of good design.
If you listen to her commentary, almost NONE of it is ever design-specific. It's all "she looks fat", "you made her look thin, yay" "I like the color" "I don't like the fit". It's never inspired, thoughtful or thought-provoking criticism.
I think she just really, really needed the work, and the producers knew it.
I would much rather see Tyra or Iman as the host. Can you IMAGINE?!?!
Suzanne: I never use catalogs. I'd rather go in the store and see all the salespeople groveling and sucking up to you.
Julia: Pardon me, I never knew they were so solicitous at the K-Mart.
