Matteau
Matteau was founded in 2014 in Sydney by Australian designers Ilona Hamer and Peta Heinsen as a contemporary luxury swimwear-and-resort-aesthetic brand specifically focused on what the founders described as 'a deliberately-Australian-and-Pacific-Coast contemporary-luxury vocabulary anchored to sustainable-fabric production and architectural-minimalist construction.' The brand has been one of the defining post-2014 Australian-anchored contemporary-luxury-swimwear brands.
The Matteau vocabulary settled around several specific products: deliberately-architectural one-piece swimwear (the brand's defining product category since 2014 — the iconic Matteau Petite Plunge one-piece, Petite Cup one-piece, and Hi-Cut bikini have been the brand's anchoring products), hand-finished bikini-set variations in deliberately-minimalist construction, deconstructed cotton-and-linen resort-aesthetic ready-to-wear (the iconic Matteau Voyager Tee, Holiday Trousers, and Beach Cover-Up programmes), and a colour palette anchored to washed-cream, oxblood, ecru, washed-charcoal, soft-pink, washed-navy, plus the brand's recurring use of natural-tan, dust-rose, sage-green, and the iconic Australian-Pacific-Coast-aesthetic colour combinations.
The brand is independent and held by Hamer and Heinsen. Matteau operates flagship retail in Sydney (Paddington — the brand's home flagship) plus international wholesale through SSENSE, Net-a-Porter, MATCHES, Mytheresa, Bergdorf Goodman, the Webster, and a curated set of contemporary-luxury-resort-aesthetic specialty retailers globally. The brand has been one of the most quietly disciplined post-2014 Australian-anchored 'sustainable-luxury-swimwear' brands.
