VICI Grey Dress with Rhinestones

I bought this dress for a work event, but it doesn’t fit! Never been worn, but didn’t come with tags when I ordered it online so it’s NWOT. I have included photos of the dress on the model as well as photos of the dress I have. I would say my photos are more true to color. There is a mesh layer that the rhinestones are attached to. The top has a boned corset inside. Such a stunning dress, just didn’t stay up on me. Please comment with any questions!
