Sometimes Mattel just can't decide what they're doing. This outfit has a lot of classy touches: Rosie's own label in each and every piece of her clothing; nice pleats on the front of her trousers; full lining on the jacket and the pants; and actual snaps on the vest, which is an actual vest and not part of the shirt. On the other hand, the red suit pieces are cheap old lady polyester, and the t-shirt is permanently attached to the pants. The main piece also fastens with velcro, but at least it's the new thinner style. Worst of all, the tailoring isn't particular good, leaving an outfit that looks a bit limp when worn.

Evaluation:
