If the garment is being custom made to fit her specifically, it's a requirement. Pro models need to have very accurate measurements on their comp cards or bios. One of the complaints many photographers had on MM was looking at a model's portfolio, deciding they liked her look and arranging a meeting, only to find the person had put on 20 pounds, was 3 inches shorter than described, had changed hair colour and had gotten a bunch of tattoos.
This is one of the reasons why it pays to hire from an agency. If you go that route, you have a reasonable expectation of the model arriving as advertised, and of the model arriving.
