Overview:Stepping into Diana Harris' Barbie room is like stepping into a miniature fashion show. Her Barbie collection features row upon row of dolled-up dolls--in their boxes-- each one more fashionable than the next. As a young girl, Diana loved to play with them and dress them up. As a Barbie collector, she finds herself drawn to the fashion-forward Barbies with designer clothes. Her Christian Dior Barbie, the Ekaterina Silkstone doll and her sweet smell PJ Roses are just a few we'll be checking out today. Joining Diana and Lisa today is Rebecca, a Barbie expert, who knows her dolls inside and out, and will have to evaluate the entire collection. Then, Rebecca will do her best to convince Diana to make a trade with her--- agree to take the special doll she knows Diana doesn't have but, in exchange, be willing to fork over one of her precious possessions.
