Black Shirt Market Report: Sales Volume, Market Share, Leading Brands & Market Trends

Gildan is the best-performing black shirt brand in July 2026, moving 21,000 units across 4 ASINs for 51.2% of Top 10 volume. Trendy Queen follows with 13,000 units (31.7%), ahead of ADOREJOY on 4,000 units (9.8%).

With 4 brands splitting the Top 10 and 92.7% 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 $9.99 to $22.24, 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, B01DSQNCF2 leads positive momentum with ▲ 300.0% MoM growth on 400 units, with B01DDG22ZS close behind at ▲ 150.0% MoM on 500 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already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date.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.
