Black velvet evening gown with silver brooch

I lost my black velvet evening gown yesterday around 3pm near the Lake Charles Civic Center on Ryan Street. It’s a floor-length size 6, brand Maison de Nuit, with a detachable silver crystal brooch at the waist and a slim satin belt. There’s a small snag on the left hem and the lining is a bit wrinkled from the ride home, but otherwise it’s in good condition. This dress has sentimental value for me because it was a gift from my late mother and I wore it to a family wedding. If anyone found it, I’d really appreciate getting it back!
