Swim Suit Market Report: Sales Volume, Market Share, Leading Brands & Market Trends

colornival is the best-performing swim suit brand in July 2026, moving 7,000 units across 1 ASIN for 25.0% of Top 10 volume. Holipick follows with 5,000 units (17.9%), ahead of ELETOP on 4,000 units (14.3%).

Volume is spread across 7 brands, with the top three holding 57.1% 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 $9.99 to $34.49, 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: B0BLNQ3C8Y booked 2K units at $29.69, with ▲ 0.0% MoM change. On the growth side, B0BRR7V9HR leads positive momentum with ▲ 200.0% MoM growth on 600 units, with B09MVZ5782 close behind at ▲ 150.0% MoM on 1K 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already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date.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.
