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

G Gradual is the best-performing bathing suit shorts women brand in July 2026, moving 7,000 units across 3 ASINs for 50.0% of Top 10 volume. Soothfeel follows with 2,000 units (14.3%), ahead of Tempt Me on 1,000 units (7.1%).

With 7 brands splitting the Top 10 and 71.4% 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 $19.98 to $19.99, 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: B0829S2NB2 booked 1K units at $17.99. On the growth side, B0C6QS28M1 leads positive momentum with ▲ 100.0% MoM growth on 2K units, with B0D2XYWZDD close behind at ▲ 33.3% MoM on 800 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already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date.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.
