Best Underwire Bikini Top Brands on Amazon US — Top 3 Brand Sales Concentration (July 2026)

Volume is spread across 9 brands, with the top three holding 54.4% between them.

Average selling prices among the leaders run from $9.99 to $27.49, which frames the price band a competing listing has to justify.

Trending Underwire Bikini Top 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, one ASIN forced its way in: B0839G2GGM booked 400 units at $19.99. On the growth side, B0GZV8QKDC leads positive momentum with ▲ 100.0% MoM growth on 200 units, with B0DFXRMK2B close behind at ▲ 100.0% MoM 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already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date.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.
