Button Down Shirt Men Market Report: Sales Volume, Market Share, Leading Brands & Market Trends

COOFANDY is the best-performing button down shirt men brand in July 2026, moving 12,000 units across 4 ASINs for 46.2% of Top 10 volume. J.VER follows with 7,000 units (26.9%), ahead of ROUWELL on 5,000 units (19.2%).

With 4 brands splitting the Top 10 and 92.3% 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 $16.99 to $29.99, 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: B0BV27DL6Y booked 3K units at $29.99. On the growth side, B09XJ4ZSMC leads positive momentum with ▲ 33.3% MoM growth on 400 units, with B0G5LFHCG5 close behind at ▲ 33.3% MoM on 400 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already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date.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.
