If I had to pick a classic line-up of models from "The Price is Right," I'd say that the all-time iconic line-up has to be Janice, Holly, and Dian from the 70s and 80s. Out of all these folks, Holly was my favorite, thanks to her sparkling smile and wholesome good looks.
My personal favorite individual TPiR model of all time, however, was Chantel Dubay. It's a terrible shame that she wasn't on the show for very long. The current batch of beauties seems to be very much interchangeable.
