Navy evening gown with pearl neckline

I was at Meadowhall Shopping Centre yesterday around 3pm after a charity gala and must have set the dress down somewhere near the service desk. I’m missing my navy blue, floor-length evening gown by Aurora Formal, size 12. It’s satin with a subtle shimmer and features a pearl-embellished neckline; there’s a small tear at the left hem from a scuff on the escalator. It means a lot to me—it was a gift from my aunt and I was counting on wearing it to an important event next month. If anyone found it, please let me know, I’d really appreciate getting it back.
