Vera-Ellen's waist size

Is that true? Did she have anorexia nervosa? (Or another type of anorexia?) While I’m aware that every body type is seen with the disease, she really looks well muscled, well hydrated and marbled with fat in all the right places in those pictures, and she was a strong dancer - her waist is small because she waist trained with a corset, not because she was underweight or wasting.
