White Maternity Dress Market Report: Sales Volume, Market Share, Leading Brands & Market Trends

ZESICA is the best-performing white maternity dress brand in July 2026, moving 2,200 units across 5 ASINs for 45.8% of Top 10 volume. chouyatou follows with 1,000 units (20.8%), ahead of BTFBM on 800 units (16.7%).

With 5 brands splitting the Top 10 and 83.3% 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 $32.50 to $53.79, 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: B0BVLHWL6M booked 1K units at $32.50. On the growth side, B0GRMY722F 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already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date.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.
