Halloween // Costume came in the mail and didn’t work at all😭

Hi! This Halloween my fiancé (m) is going to be victor Frankenstein, and I (f) am going to be the creature. I currently have my hair half bleached similarly to the bride of Frankenstein. We are not looking to copy costumes from the movie, but to keep the same vibe. I bought a gray dress and black corset, and they both fit, but don’t look good at all. It took a while to decide on what to get, and now it’s uncomfortably close to Halloween! I would like any advice on what to get! Any ideas you have! Think Disney bounding but genderbent Frankenstein! And still with that gothic theme! Thank you!
