Girls Swimsuit Size 8 Market Report: Sales Volume, Market Share, Leading Brands & Market Trends

The Children's Place is the best-performing girls swimsuit size 8 brand in July 2026, moving 1,200 units across 3 ASINs for 22.6% of Top 10 volume. PROALLO follows with 1,000 units (18.9%), ahead of Fruit of the Loom on 800 units (15.1%).

Volume is spread across 8 brands, with the top three holding 56.6% between them. No single label controls the shelf, which usually leaves room for a well-differentiated listing to take share without outspending an incumbent. Average selling prices among the leaders run from $11.99 to $19.12, 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, 3 ASINs forced its way in: B0FL87445G booked 800 units at $11.99, with ▲ 100.0% MoM change.

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already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date.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.
