Okay, now I know what the whistle bag is. There was one on ebay (authentic?) for $499. I'm trying to search on what that wristlet style is. The SA at NM didn't know much about B-bags either.
Oops, the whistle bag is not the one on Ebay for $499. Those were Mirror bags but they look very similar to whistle bags. The whistle bag is the second photo on this page: Balenciaga
