Syntactic actants

Actant 1: whose waist it is
(a) Genitive
(b) Possessive
Стан девушки был тонкий и гибкий. The girl's waist was slender and lithe.
Широкий пояс охватывал её стан. The wide belt encircled her waist.
NB When the word стан functions as a subject and does not have a descriptive modifier, the construction стан у + Genitive is often preferred to (a) and (b), above:
Стан у девушки был тонкий и гибкий. The girl's waist was slender and lithe.
