Reception months after wedding ceremony

Hi everyone!


My husband and I recently eloped in Las Vegas. It was just the two of us so of course we want to celebrate our love with our family! Since we didn’t do it in a traditional way I have a few questions. Such as do I set up a registry? (I didn’t have a shower). Should I keep it casual or treat it as an actual reception that would typically be directly after? What kind of food??
I know I have a lot of questions so if anyone can give me any advice on anything I’d appreciate it!!💍
