Wizard Costume Market Report: Sales Volume, Market Share, Leading Brands & Market Trends

Rhode Island Novelty is the best-performing wizard costume brand in July 2026, moving 1,400 units across 2 ASINs for 37.8% of Top 10 volume. Disguise follows with 500 units (13.5%), ahead of Watayo on 400 units (10.8%).

With 8 brands splitting the Top 10 and 62.2% of volume sitting with three of them, this is a concentrated shelf — the leaders hold multiple listings or one very high-velocity ASIN, so a new entrant competes against established review moats rather than an open field. Average selling prices among the leaders run from $8.29 to $28.94, which frames the price band a competing listing has to justify.

Based on July 2026 data, this shortlist surfaces the two kinds of ASIN worth keeping an eye on — the ones that just broke into the Top 10, and the ones growing fastest month over month. Specifically, one ASIN forced its way in: B0G1HBCWM3 booked 200 units at $34.99. On the growth side, B083TMQVMY leads positive momentum with ▲ 200.0% MoM growth on 300 units, with B0FFSQC6S5 close behind at ▲ 100.0% MoM on 400 units.

The two signals carry different weight. A fresh entrant means share has already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date. A steep growth rate works as the earlier warning: it marks demand that is still compounding, usually a month or two before the ranking catches up to it.
