As I have said a number of times on these boards, none of the models look like me. I understand seeing the product on a body, hanger appeal is usually not the way to judge a garment (see most episodes where this is stated on "What Not to Wear" lol). But I always use the garment measurements for sizing and my own opinion on if I like the appearance and or quality of the item.
I will say, the static Belle shows always have Katia, a tall glass of water and a tiny waist, and Jamie who is tall too, but a curvy build. There should be some middle ground, which I think they did better during her last TSV for the zipper blouse. I like that they have added the wheelchair models and others who different challenges, but they are also only sprinkled in few and far between.
