Too many people now are looking at last year when Halloween due to COVID-19 was dicey.
Today, many people are interested in Halloween costumes and makeup. Families want to join in the festivities so this is not only for children anymore but also for the parents and surprisingly for people's pets.
Most retailers are scared of these product ranges as if they do not sell over Halloween, they are stuck with unsellable items. Still, many of the popular items are not Halloween items, e.g. facepaint, vampire teeth, fairy costumes and makeup. So I would suggest while there is time to look into it.
