Under Shirts For Women Market Report: Sales Volume, Market Share, Leading Brands & Market Trends

ANRABESS is the best-performing under shirts for women brand in July 2026, moving 18,000 units across 4 ASINs for 47.4% of Top 10 volume. Trendy Queen follows with 7,000 units (18.4%), ahead of PINKMSTYLE on 5,000 units (13.2%).

With 6 brands splitting the Top 10 and 78.9% 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 $8.49 to $19.98, 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. On the growth side, B07JN6Q9YJ leads positive momentum with ▲ 150.0% MoM growth on 500 units, with B0F5WNKZRS close behind at ▲ 75.0% 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already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date.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.
