Makeupjunkie is right, there are no "special" models for couture. Couture models are the same models you would see during fashion week, except during couture fashion week.
The only difference is usually the shorter girls are left out of it minus Luca Gadjus who seems to do it more than the other short girls. The designs are much more elaborate and intricate, thus needing the height of the taller girls.
Design houses like Chanel and Christian Dior run both Haute Couture lines, and ready to wear lines.
Regular ready to wear Chanel is not the same as Haute Couture Chanel.
