White One Piece Swimsuit Market Report: Sales Volume, Market Share, Leading Brands & Market Trends

Holipick is the best-performing white one piece swimsuit brand in July 2026, moving 2,200 units across 5 ASINs for 47.8% of Top 10 volume. Lilosy follows with 1,000 units (21.7%), ahead of SUUKSESS on 900 units (19.6%).

With 5 brands splitting the Top 10 and 89.1% 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 $19.99 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: B0GJQ7GG1Q booked 100 units at $35.99. On the growth side, B0GY3ZYBGH leads positive momentum with ▲ 133.3% MoM growth on 700 units, with B0CYWFCCQ1 close behind at ▲ 100.0% MoM on 100 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already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date.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.
