What is Acacia?

Acacia is a swimwear and resortwear label from Hawaii, founded in 2010 by Hawaii native Naomi Newirth. The brand's look is often described as Hawaiian beach chic, combining minimal swimwear with relaxed clothing for life by the ocean.

Products and positioning

Acacia made its name with cheeky-cut bikini bottoms, offering a revealing cut that is not a thong, a style Newirth was among the first to popularise. Alongside swimwear the label produces a ready-to-wear collection, and it has since expanded into men's and children's clothing. Its designs draw on global influences filtered through an island lifestyle.

  • Bikinis and one-piece swimsuits
  • Beach-chic ready-to-wear
  • Menswear and childrenswear additions

Approach

Newirth employs local women designers, and the company has pursued sustainable practices as it has grown. Its roots on Maui and in Hawaii's surf and beach culture remain central to its identity.

Why it matters

Acacia is one of the Hawaii-based labels that turned a local beach aesthetic into a nationally recognised swimwear brand, and its cheeky cut influenced the wider bikini market.
