Marketplaces & other options

• eBay Australia and Amazon Australia — wide price range, new and second‑hand options (good for bargains or hard‑to‑find styles).
• Boutique designers — look on THE ICONIC, David Jones or direct brand sites for Australian designers (e.g., AJE, Camilla & Marc).

Quick shopping tips

• Sizes: Australian sizing uses AU numbers (4, 6, 8…); check each site’s size chart and product measurements. (theiconic.com.au)
• Returns: review the returns policy before buying — THE ICONIC and many Aussie retailers offer free or easy returns, but policies vary (and some international fast‑fashion sites have introduced stricter return rules). (theiconic.com.au)
• Delivery: look for free‑shipping thresholds and express options if you need the dress quickly. (davidjones.com)
• Payment/finance: many Australian retailers accept Afterpay, Zip or Klarna if you want instalments (check the product page/checkout).

If you’d like, I can:

• Narrow these to a budget (cheap / mid / designer), an occasion (work, wedding guest, formal), or a size range (petite/plus), and give direct links to current dress selections.
