sana_saleem, in "senin giysilerin bende" i can say that "bende" act as the verb of the sentence: "bende"= "is at me". Do you remember all the sentence of this type in the locative skill? As: "cay onlarda"="we have the tee", "elmalar sende"="you have the apples", "ördekler bizde"="we have the ducks"......
English always needs a verb. So it would have to be "Your clothes are mine."
That said, the sentences have different meanings.
"Your clothes are mine." means that the clothes had been yours, but they are no longer yours, they are mine now.
"I have your clothes." means that the clothes still belong to you, but I have them because I borrowed them, or you left them in my car or something.
