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

Holipick is the best-performing bathing suit brand in July 2026, moving 11,000 units across 4 ASINs for 47.8% of Top 10 volume. ELETOP follows with 7,000 units (30.4%), ahead of Daci on 3,000 units (13.0%).

With 5 brands splitting the Top 10 and 91.3% 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 $17.99 to $39.99, 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: B09M6RDNX9 booked 3K units at $17.99. On the growth side, B0D9K6LQT9 leads positive momentum with ▲ 250.0% MoM growth on 700 units, with B0GT9KGPY7 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already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date.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.
