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

Holipick is the best-performing black swimsuit brand in July 2026, moving 11,000 units across 4 ASINs for 57.9% of Top 10 volume. Blooming Jelly follows with 4,000 units (21.1%), ahead of Herseas on 2,000 units (10.5%).

With 5 brands splitting the Top 10 and 89.5% 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 $27.99 to $34.99, 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. On the growth side, B0DSGRT4QY leads positive momentum with ▲ 66.7% MoM growth on 1K units, with B0DLT2Z98W close behind at ▲ 50.0% MoM on 900 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already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date.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.
