YA, I wish Jessica Stam can appear in major campaigns again.
Raquel Zimmerman, Daria Werbowy, Anja Rubik and even Stella Tennant often appear in big ads even they don't do runways that much anymore.
Jessica Stam is listed 'Industry icon', so as other big names. Why doesn't the same thing happen to her??
One of the reason I think, is that Jessica has a very unique face and vibe that she won't fit in many of the campaigns nowadays, unlike Raquel or Daria, both of their looks are almost suitable for everything from beauty ad to clothes ad, or even cell phone ad.
Jessica only gets editorials and ads when the theme allows her to do her thing.
Besides, the doll face era has already gone, Gemma Ward, Sasha, Lily Donaldson are not that active in modeling industry anymore. Jessica seems to be left without any companies. She can no longer do eds and ads with the type of girls like herself.
Today's time does not belong to her anymore, the fashion industry needs another type of models for their brand. This may be the reason why many today's new models are quirky, boyish, they don't have that grace old models have.
You may notice Jessica has tried to break herself away from the doll face category as she is not just sitting there still, showing her magnificent doll face like the old times in recent eds. You can see there is more movement and attitude in her latest work.
The next reason I think is no matter how you just can't see Raquel, Karen Elson and Daria in the same level as Jessica. They are always in a higher position than Jessica even though they are all industry icons. Therefore designers always consider them for ads first.
