Where can I find a womens blouse that resembles the one Kate
Beckinsale wore in Van Helsing? It's the white blouse with the red
embroidery on it.

If you have a pic send it to

they can remake just about anything if they have an idea what you want.
Was that a movie? never heard of it if it was but if it was a movie
you could watch the credits for wardrobe and contact them for the
information. It may have been custom made though, one of a kind, who
knows.
