It's actually a beautiful piece but probably not placed that well for the event. Im looking forward to seeing it on a different, more flowing, fabric and placed either on the should or as a true stomacher.
I don't think there is a missing tassel... just one short and one longer tassel.

I think the missing tassel is hiding under the Garter sash 😜
