Honestly I wouldn't know, mainly because it's ultimately up to what the industry sees in Emily.
Since we're talking hypothetical terms , I think she would fit the Italian labels like Dolce & Gabbana and so forth but I don't know. For me, it would work if we see her doing more runway to see versatility and how models look when designers release new collections.
I wish she had a better runway work but doesn't mean Emily hasn't booked a lot of great gigs like face of Giorgio Armani 'Acqua Di Gioia' fragrance and of course Maybelline. I just think she's really underrated as a HF model.
EDIT: found an older behind the scenes video with Emily and the other Maybelline models for "Baby Lips" lipbalm.
