Volume is spread across 9 brands, with the top three holding 51.1% between them.

Average selling prices among the leaders run from $9.99 to $17.49, which frames the price band a competing listing has to justify.

Trending Kids Swimsuits Products — Growth Leaders & New Top 10 Entrants
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: B0D2WFZWM5 booked 500 units at $9.99, with ▼ 28.6% MoM change. On the growth side, B0GT4JVW3F leads positive momentum with ▲ 300.0% 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already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date.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.
