Polka Dot Swimsuit Market Report: Sales Volume, Market Share, Leading Brands & Market Trends

WDIRARA is the best-performing polka dot swimsuit brand in July 2026, moving 700 units across 2 ASINs for 21.2% of Top 10 volume. ZAFUL follows with 700 units (21.2%), ahead of Holipick on 500 units (15.2%).

Volume is spread across 7 brands, with the top three holding 57.6% between them. No single label controls the shelf, which usually leaves room for a well-differentiated listing to take share without outspending an incumbent. Average selling prices among the leaders run from $22.31 to $39.49, 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, 3 ASINs forced its way in: B0GVMW95HY booked 400 units at $38.99, with ▲ 100.0% MoM change.

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already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date.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.
