Here are popular apps used in Singapore to buy luxury clothing and accessories (new and/or authenticated pre‑owned), with a short note about each:

• ZALORA (ZALORA Luxe) — regional fashion app with a dedicated luxury/designer section for Singapore; sells new designer brands and also lists pre‑owned pieces via partners. (ZALORA.sg)

• Farfetch — global luxury marketplace app that carries many designer boutiques and ships to Singapore (new items from multiple merchants). (buyandship.com.sg)

• NET‑A‑PORTER (and Mr Porter) — premier online luxury retailer with an app and Singapore delivery options (express shipping, signature service). (NET-A-PORTER.com)

• Mytheresa — luxury retailer offering international designer clothing, shoes and accessories with a Singapore site/checkout and local shipping/taxes displayed in SGD. (Mytheresa.com)

• MatchesFashion / SSENSE — international luxury e‑tailers with apps/sites that ship to Singapore (popular for new-season designer stock). (sg.style.yahoo.com)

• Vestiaire Collective — large authenticated marketplace app for pre‑owned designer goods (bags, clothing, accessories) operating in Singapore. (apps.apple.com)

• Carousell (Carousell Luxury) — Singapore‑founded classifieds/recommerce app with a dedicated luxury/resale channel and verification services; has strong local presence. (press.carousell.com)

• StyleTribute — Singapore-based curated pre‑owned luxury marketplace/app (buy & sell; concierge options). Note: when using smaller/local resale platforms, check recent seller/buyer reviews and payment/authentication policies. (thebeat.asia)

• Reebonz — historically a Singapore luxury marketplace/app (new and pre‑owned). (If considering Reebonz, be aware of past business changes and check current operational/status updates before transacting.) (sg.wantedly.com)

Quick tips

• New‑item luxury: Farfetch, NET‑A‑PORTER, Mytheresa, MatchesFashion and SSENSE are best for current-season pieces. Check shipping costs, duties and delivery times at checkout. (NET-A-PORTER.com)
• Pre‑owned/authenticated: Vestiaire Collective, Carousell Luxury, StyleTribute (and some Reebonz services historically) focus on authenticated resale—good for deals but verify authentication and seller protections. (apps.apple.com)

If you want, I can:

• Narrow this to apps that currently have the fastest delivery to Singapore, or
• Show only resale apps with in‑app authentication and buyer protection, or
• Provide the App Store / Google Play listings for any of the apps above.
