Black velvet evening gown with silver beaded collar

I lost my black velvet evening gown yesterday around 3pm near The Mailbox on Wharfside Street in Birmingham. It's a floor-length gown, size UK 8, from the brand Reiss, with a delicate silver beaded collar and a detachable chiffon cape. There are a few scuffs along the hem from walking on the pavement, but otherwise it's in good condition. This dress was my late grandmother's gift, and it means a lot to me—I'm supposed to wear it to my sister's wedding this weekend, and I’m really hoping someone found it and can return it. If you found it, please email me at [email protected].
