Grace Karin Tops Market Report: Sales Volume, Market Share, Leading Brands & Market Trends

RUMIA is the best-performing grace karin tops brand in July 2026, moving 2,000 units across 1 ASIN for 26.3% of Top 10 volume. GRACE KARIN follows with 1,700 units (22.4%), ahead of Zeagoo on 1,500 units (19.7%).

With 6 brands splitting the Top 10 and 68.4% 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 $8.05 to $19.99, 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, 2 ASINs forced its way in: B0H2915PVG booked 1K units at $12.99. On the growth side, B0DQW6MPJR leads positive momentum with ▲ 100.0% MoM growth 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already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date.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.
