Best Plus Size Panties Brands on Amazon US — Top 3 Brand Sales Concentration (July 2026)
INNERSY is the best-performing plus size panties brand in July 2026, moving 8,000 units across 1 ASIN for 19.0% of Top 10 volume. Sth Big follows with 8,000 units (19.0%), ahead of UNDER THE SEA on 6,000 units (14.3%).
Volume is spread across 9 brands, with the top three holding 52.4% 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 $9.99 to $14.99, which frames the price band a competing listing has to justify.

Trending Plus Size Panties Products — Growth Leaders & New Top 10 Entrants
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: B07FT5MSM9 booked 2K units at $22.94. On the growth side, B08679XH5S leads positive momentum with ▲ 100.0% MoM growth on 2K units, with B0G2YBBTLF close behind at ▲ 100.0% MoM on 2K 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already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date.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.
