Halloween // So my girlfriend and I have awesome costumes but no plans

It’s our first Halloween together so we decided on cosplaying as Beast Boy and Raven for Halloween. The costumes are coming along great we have everything mostly finished but uh We don’t have plans Originally we were going to hang out with another couple and watch movies but we sorta don’t talk to them anymore(long story) What are some ideas to do for Halloween that don’t involve large gatherings We just need an excuse to wear the costumes all day tbh
