Prada Group continues to defy luxury’s downturn, reporting nine-month net revenues up 18 percent year-on-year.

Growth was powered by Miu Miu, whose wonky yet wearable wardrobe wrapped in a message of empowered girlishness for all ages fuelled retail sales that more than doubled in the third quarter, rising 105 percent year-on-year. The eye-popping expansion is all the more impressive as it comes on top of 58 percent growth last year.

Prada’s retail sales slowed compared to the first half of the year, but remained in positive territory. Third-quarter retail sales rose 2 percent year-on-year.

The group’s emphasis on innovative products and marketing activities that maintain its cultural clout has helped the group to continue to outperform rivals in a slowing luxury market, which has seen sales sputter for even the industry’s biggest and most powerful players. LVMH reported fashion sales down 5 percent in the third quarter; Gucci owner Kering’s revenues plunged 15 percent.

Prada, Hermès and Brunello Cucinelli are the only brands to have reported rising sales this quarter.
