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

SHAPERMINT is the best-performing shapewear underwear brand in July 2026, moving 10,000 units across 1 ASIN for 32.3% of Top 10 volume. OEAK follows with 4,000 units (12.9%), ahead of SHAPERX on 3,000 units (9.7%).

Volume is spread across 9 brands, with the top three holding 54.8% between them. No single label controls the shelf, which usually leaves room for a well-differentiated listing to take share without outspending an incumbent. Average selling prices among the leaders run from $16.98 to $38.99, 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, 2 ASINs forced its way in: B0CN9C47Y1 booked 3K units at $8.52. On the growth side, B0FB3K6GR5 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already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date.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.
