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

CUPSHE is the best-performing cupshe one piece swimsuit brand in July 2026, moving 4,300 units across 6 ASINs for 44.8% of Top 10 volume. Holipick follows with 3,000 units (31.3%), ahead of B2prity on 1,300 units (13.5%).

With 4 brands splitting the Top 10 and 89.6% 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 $26.14 to $39.66, 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, 2 ASINs forced its way in: B0B9GK4CNJ booked 1K units at $39.99. On the growth side, B0GY45WFX7 leads positive momentum with ▲ 100.0% MoM growth 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already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date.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.
