Having Halloween party is only showing once a year. Many people save money before the day of the big event, and some also prefer to make it simple. It really depends on the situation. If you are having a problem on a budget right now, then make it simple. Being simple is not bad at all, it is way better than pretending you have everything but has nothing in the end. On the other hand, you can also spend if you think you have enough funds for this. You don’t need to think of the budget since you prepared for this event since it only takes once a year.
It really depends on what budget you are having. Or if you already invited a lot of important people before, then you can make it different now. You can also celebrate it alone or with your family. It really depends on what you prefer for that event. The most important is you are comfortable about it.
