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

SHAPERMINT is the best-performing plus size shapewear brand in July 2026, moving 23,000 units across 7 ASINs for 79.3% of Top 10 volume. SHAPERX follows with 4,000 units (13.8%), ahead of SHAPELLX on 2,000 units (6.9%).

With 3 brands splitting the Top 10 and 100.0% 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 $19.99 to $39.49, 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: B0CG7L63JZ booked 4K units at $32.29. On the growth side, B0DFCHV1DY leads positive momentum with ▲ 100.0% MoM growth on 400 units, with B0F91CYWXX 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already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date.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.
