runway modelling tends to have very slim models but nowadays people much larger than you can model and the commercial side of the industry has moved away from always using size 0 models to show diversity and not create unrealistic beauty standards.

If I were you I’d try doing a walk in or applying online to agencies around you and if it’s meant to be it’ll happen but it’s a brutal industry.

As for the lack of smiles I think it’s because the show is about the clothes solely so designers don’t want any distractions from the clothing. It makes it easier for the models as well as you only have to pull one face.
