Plus Size Tube Top Market Report: Sales Volume, Market Share, Leading Brands & Market Trends

Trendy Queen is the best-performing plus size tube top brand in July 2026, moving 8,000 units across 2 ASINs for 53.7% of Top 10 volume. CHICGAL follows with 2,900 units (19.5%), ahead of iGENJUN on 1,000 units (6.7%).

With 7 brands splitting the Top 10 and 79.9% 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 $6.79 to $14.49, 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: B07FRC9ZRN booked 600 units at $9.98, with ▲ 200.0% MoM change. On the growth side, B0DXKGM5X1 leads positive momentum with ▲ 100.0% MoM growth on 100 units, with B0GTMHK953 close behind at ▲ 50.0% MoM on 300 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already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date.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.
