The premise of WNTW is that women who are "ugly and unfashionable" (on the show, the two are always equated) are transformed, becoming "beautiful, put-together and self-confident" (once again, it seems you can't be one without the others). In the process, the hosts make fun of her old wardrobe, throwing most of it out, and ridicule her shopping choices until she conforms to their dictated "rules of good shopping."
It drives me nuts that WNTW picks women with problems much bigger than their wardrobe, and pretends it can all be fixed by conforming to "the right look". The show presents fashionable dress as a black and white issue: if you dress like we want you to, you're wonderful. Otherwise, you're obviously hiding deep-seated fears, low self-esteem and/or other tragic personal issues. That's the ONLY explanation possible. While I agree that for some women, a "sloppy" wardrobe might be a symptom of a deeper problems, it's certainly not the cause, and changing how they dress won't change their lives without a lot of work in other areas.
When your "truth" is applied to someone else, it is no longer the truth. It becomes an "opinion," what you think.
