This is a generic answer to any dilemma: If you have to ask whether or not something is proper, that illustrates that there is doubt in your mind. That doubt is there for a reason, your common sense is telling you that it isn't acceptable. However, there is another side of you that is looking for an excuse to do just the opposite, and posting here to get others to make you feel better about it.

Now, to address this specifically: Nothing wrong with dressing up and having fun, but going from door to door is for kids. Adults can go to clubs, have parties, and buy their own candy anytime they want. I don't understand why an adult would want to spend their time on Halloween going door to door for candy (unless to accompany children, and even then, the candy is just for the kids) when there are other options that are so much more fun.
