^Not that I don't trust her friend, of course, but it sounds like maybe she was shooting a lookbook/advertorial for the brand and thus being unable to do castings/shows beforehand...but I guess the definition of "exclusive" is becoming kind of muddled overall these days
The important thing is that she is evidently considered a muse for the designer, and doing jobs consistently for Pucci in the present/future would definitely be more worthwhile than just being dubbed "exclusive" for one time.
