Posse dresses are made by Posse, the Australian womenswear label founded in 2016 by Danielle Mulham, and they cover every length from short cotton shifts to silk maxi slips. Most are cut from natural fabrics such as cotton, linen, silk and Tencel, many belong to a matching set of tops, skirts and shorts in the same fabric, and the brand says most styles fit true to size in letter sizes XXS to XXL.

Australian fashion brands are known for clothes made for heat, light and a life spent partly outdoors: printed resort dresses, linen and cotton separates, sculptural evening gowns and sharp tailoring. Labels such as Zimmermann, Aje, Scanlan Theodore, Camilla and Marc, Alex Perry and Posse sit at the luxury end, and many now sell worldwide. This editor's guide groups the Australian labels Coveti stocks by what each one does well, with a comparison table to help you choose.
