Cupshe One Piece Swimsuits Women Market Report: Sales Volume, Market Share, Leading Brands & Market Trends

CUPSHE is the best-performing cupshe one piece swimsuits women brand in July 2026, moving 3,800 units across 5 ASINs for 50.7% of Top 10 volume. Holipick follows with 1,200 units (16.0%), ahead of Eomenie on 1,000 units (13.3%).

With 5 brands splitting the Top 10 and 80.0% 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 $36.99 to $39.59, 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: B0B9GK4CNJ booked 1K units at $39.99. On the growth side, B0DL5PFBVG leads positive momentum with ▲ 100.0% MoM growth on 400 units, with B0FH2DQ4Y8 close behind at ▲ 100.0% MoM on 200 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already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date.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.
