Fajas Market Report: Sales Volume, Market Share, Leading Brands & Market Trends

FeelinGirl is the best-performing fajas brand in July 2026, moving 9,000 units across 3 ASINs for 30.0% of Top 10 volume. SHAPERX follows with 6,000 units (20.0%), ahead of Sports Research on 4,000 units (13.3%).

With 7 brands splitting the Top 10 and 63.3% 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 $27.95 to $33.99, 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, B09C8L38V9 leads positive momentum with ▲ 40.0% MoM growth on 700 units, with B0DJ8XP8GF close behind at ▲ 40.0% MoM on 700 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already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date.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.
