It depends. As you may know, there are many models of all shapes and sizes, from plus-sized ones to petite ones and those in between. A person's body shape is not the most important aspect of their brand, it is their measurements and how they present themselves on the runway or in a photograph.
In some cases, agencies prefer women who have more curves, while other agencies prefer those who are thinner or more athletic. There is no question that being confident in your skin is the most crucial thing, as well as knowing you can carry off any look you want.
