Twenty Third by Deanne

Twenty Third by Deanne sells women’s occasion-wear dresses, two-piece sets, jumpsuits and coordinating accessories. Most pieces sit between AUD $180-$380, placing the label in the mid-range bracket. Sales are handled entirely through the brand’s own e-commerce site with domestic express shipping and AfterPay available. The label is known for form-fitting silhouettes cut from stretch crepe and satin that feature thigh-high splits, open backs and built-in corsetry. New limited-edition colourways drop every 4-6 weeks and are promoted with size-inclusive imagery (6-18 AU). Their “Cannes” midi and “Capri” maxi are repeat sell-outs that regularly appear on Instagram event tags. Customers are 18-35-year-old Australian women shopping for races, weddings, birthdays and holidays who want an instantly recognisable “Instagram” dress without designer price tags. They value fast turnaround, inclusive sizing and trend-led cuts that photograph well. Twenty Third competes in the crowded social-first occasion-wear space dominated by budget fast-fashion labels and higher-priced designer diffusion lines. It differentiates by offering mid-tier quality fabrics, consistent fits across repeat styles, rapid micro-drops and strong influencer proof, positioning itself as an accessible go-to for statement event dressing.
