Upon the use of possessive adjectives with a noun

[Nfqufktc]

I would appreciate it if you could clear up the following point:


Here is an excerpt from the text which is located at https://lingust.com/espa%C3%B1ol/esp...lecci%C3%B3n15
”sus vestidos son bonitos ... tu vestido también es bonito ... nuestros vestidos ya no están de moda ... nuestras faldas son demasiado largas…”

The given answer is “her dresses are beautiful ... your dress is also beautiful ... our dresses are out of fashion already ... our skirts are too long ...”


1. Why is it that they give “her dresses” for an answer? Couldn’t it be translated as “his dresses” as well?
And the context cannot be used as an excuse. Jose is sick and half asleep. He is just getting snatches of their conversation. His sister and her girlfriend could be talking about him (we already know that the girlfriend is sweet on him), about the latest rock star and so on.
2. Could the girls have made it clearer by using “sus vestidos de él” or, for example, “los vestidos de Bon Jovi”?
