Here are the top fashion-shopping websites in Australia (what they’re best for). I’ve included a mix of national marketplaces, fast-fashion, mid‑range and luxury sites so you can pick by price, brands and shipping.

• THE ICONIC — Australia’s biggest dedicated online fashion destination: huge range (local + international brands), fast delivery/returns and strong activewear, streetwear and contemporary labels. (en.wikipedia.org)
• Myer — major department-store site with wide brand selection across womenswear, menswear, shoes and beauty; good for mid-to-upscale purchases and frequent sales. (en.wikipedia.org)
• David Jones — department-store retailer known for premium and designer labels, beauty and formalwear; strong in luxury and occasion dressing. (ecommerce.com.au)
• ASOS (including ASOS AU) — fast-fashion and trend-led styles, great for budget-friendly, youthful pieces and lots of size/brand variety. Popular with frequent sales. (who.com.au)
• Cotton On — Australian fast-fashion chain with affordable basics, casualwear and accessories; large footprint and easy online shopping. (ecommerce.com.au)
• SHEIN — high‑volume, very budget‑oriented fast fashion (huge selection; mixed quality—shop reviews/sizes carefully). Statista traffic data shows it ranks highly in Australian visits. (statista.com)
