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

Rasta Imposta is the best-performing banana costume brand in July 2026, moving 800 units across 3 ASINs for 34.8% of Top 10 volume. MeoIsDaBest follows with 600 units (26.1%), ahead of Spooktacular Creations on 500 units (21.7%).

With 6 brands splitting the Top 10 and 82.6% 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 $6.99 to $24.49, 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: B09QT69CQX booked 100 units at $16.10, with ▲ 100.0% MoM change. On the growth side, B07H45M5TQ leads positive momentum with ▲ 33.3% MoM growth 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already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date.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.
