While I do like this show, I admit it is far from perfect. It has a lot of great ingredients, it just doesn't seem that they know how to put them together.
The Meet the client ("we'll be there in 20 minutes") thing is incredibly artificial. It's almost as bad as MTV's Pimp My Ride's. I mean I know that pretty much every reality tv show does this staged first encounter thing (wait, if they're just rolling up to the person's house, then how did the cameraman get inside the house to show them opening the door?), but they do it really inorganically.
I have to defend them with the underwear thing, with some reservations. Good quality, properly fitting foundation garments (bras, panties, slimmers, hosiery, etc) are essential for making good clothing look great. It's not about whether it's expensive, it's about whether it's doing what it needs to do. The BBC's WNTW set the stage for this, and I've always have felt that TLC's version has been really lax on it, only covering it in the extreme cases. Why give someone a great new wardrobe when they're going to wear saggy, holey underwear under it. Unfortunately the way they've gone about emphasizing this is designed more to titillate (and to give Veronica Webb a catch phrase) than to underscore the importance of good underwear.
I think that this show could become a better show over time, but it does need some work if they want it to be a great show.
