Red Bra Market Report: Sales Volume, Market Share, Leading Brands & Market Trends

COCOMARTS is the best-performing red bra brand in July 2026, moving 7,800 units across 2 ASINs for 48.4% of Top 10 volume. OEAK follows with 4,800 units (29.8%), ahead of CRZ YOGA on 1,500 units (9.3%).

With 6 brands splitting the Top 10 and 87.6% 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 $14.77 to $29.33, 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: B099Z9ZZPK booked 400 units at $14.94, with ▼ 20.0% MoM change. On the growth side, B0FS1DBXTG leads positive momentum with ▲ 250.0% MoM growth on 7K units, with B0DHSP1S5D 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already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date.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.
