Here are popular places to buy trendy clothes online in Australia, grouped by what they’re best for:

• Multi-brand marketplace (fast shipping, lots of styles): THE ICONIC — big Australian retailer carrying local & international labels, free standard shipping over ~A$75 and easy 30‑day returns. (theiconicsupport.zendesk.com)

• Trend-forward international fast-fashion & marketplace: ASOS (AU) — lots of trend pieces, wide size range, and Australia delivery options (ASOS Premier subscription for faster/free shipping). Good for quick-styled looks and lots of new arrivals. (asos.com)

• Young-women/viral styles (social-media driven): Princess Polly — regularly updated, “Instagram”/TikTok‑popular pieces; free express shipping over A$60 and same‑day dispatch options in metro areas. (princesspolly.com.au)

• Aussie womenswear focused on party/dressy trends: Showpo — local brand with lots of occasionwear and a simple returns portal (store credit/refund options). (showpo.zendesk.com)

• Second‑hand, vintage & resale (more sustainable/trendy finds): Depop — great for unique streetwear, retro pieces and small‑seller vintage; buyer/seller shipping and protections for AU users. (depophelp.zendesk.com)

Other useful sites to browse (men’s, basics, high‑street, designer):

• Zara Australia, UNIQLO Australia, Cotton On — high‑street staples and basics with Australian sites and local delivery.
• Myer and General Pants Co — department/store and streetwear options.
• Boohoo/AU and PrettyLittleThing — budget trend pieces.
• Farfetch / Net‑a‑Porter / Cettire — designer and luxury marketplaces (check authenticity/returns policies first).

Quick shopping tips:

• Check shipping thresholds and estimated delivery times (metro vs regional).
• Read each store’s returns policy before buying (some “final sale” items aren’t returnable).
• Use the site’s “New In” / “Trending” filters or follow brand accounts on Instagram/TikTok for what’s current.
• For sustainability or unique styles, search resale sites (Depop, Vinted, eBay, Etsy).

If you want, I can make a shorter list for a specific category (women’s dresses, men’s streetwear, sustainable brands, size-inclusive stores, or a budget range).
