Fashion Inspiration?

Carmen Dell Orefice in 1954 Revlon ad

Monogram Allure

I think it's a great copy. I wonder how they get away with it. Apparently iconic images are not copyrighted. What about fashions?

I ordered this Monogram doll because of the outfit and it doesn't bother me that it was copied. I just can't believe that there is no copyright protection. I remember that a few years ago Jason Wu got involved in some kind of movement to protect designers' work. The copying of designs for dolls was brought up on the boards shortly after that. I think that movement sort of fizzled.
