Maternity Shapewear Market Report: Sales Volume, Market Share, Leading Brands & Market Trends

SHAPERX is the best-performing maternity shapewear brand in July 2026, moving 9,000 units across 6 ASINs for 50.0% of Top 10 volume. SHAPERMINT follows with 3,000 units (16.7%), ahead of Walifrey on 2,000 units (11.1%).

With 5 brands splitting the Top 10 and 77.8% 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 $7.99 to $36.99, 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: B07QMX88QG booked 3K units at $28.60. On the growth side, B0GX545KB3 leads positive momentum with ▲ 100.0% MoM growth on 400 units, with B09N3CXXCX close behind at ▲ 50.0% MoM on 600 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already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date.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.
