Some of my friends fear that because they need to buy plus size costumes, they may end up by paying more because the costumes need more fabric, as they are bigger than average size ones.

Is this true or not? It depends. I’ve found shops which display the same prices, no matter what size of costumes you want to purchase. Nonetheless, some others, and especially for high-quality costumes, prices for XXL and XXXL outfits could be slightly bigger than the average ones. That’s normal, in case of expensive materials. But the majority of Halloween costumes available on the market aren’t using such pricey materials, as they don’t need to last for too many years. After all, for how many times can somebody wear the same costume?
