"I have my own costume."

Translation: Ho il proprio costume.

Hi can someone please explain why the translation is: Ho il proprio costume and NOT: ho il mio proprio costume

I suspect the word "proprio" includes "mine". I've never met "proprio" before.

The only subject in the sentence is "I", so I suspect it is because the context of "one's own" (proprio) is not ambiguous.
