Here are popular mobile apps you can use in Singapore to buy (and in some cases sell) luxury clothing, bags, shoes and accessories — grouped by type and with notes on what each offers.

International multi‑brand luxury retailers (apps, ship to SG)

• Farfetch — global luxury marketplace (designer boutiques + pre‑owned section). (apps.apple.com)
• NET‑A‑PORTER (and Mr Porter / THE OUTNET) — high‑end women’s (and men’s) luxury editorials + shopping. (apps.apple.com)
• Mytheresa — curated luxury edit with international shipping. (apps.apple.com)
• MatchesFashion — multi‑brand luxury retailer with app and worldwide delivery. (search listings available in app stores.) (apps.apple.com)
• SSENSE — luxury + designer streetwear with SG App Store listing and international delivery. (apps.apple.com)

Regional / Southeast Asia apps that stock premium & designer labels

• Zalora (SG) — large SEA fashion app with a dedicated “Luxury / Premium” section carrying designer bags, watches, fragrances and accessories. (apps.apple.com)

Pre‑owned / resale and consignment apps (popular in Singapore)

• Vestiaire Collective — global authenticated pre‑owned designer marketplace (app available in SG). (apps.apple.com)
• The Luxury Closet — marketplace for new & pre‑owned designer items, ships regionally/internationally (app available). (apps.apple.com)
• Carousell — Singapore’s classifieds/recommerce app with dedicated luxury/certified listings and programmes (widely used locally). (brandradar.org)

Singapore‑founded / local marketplaces

• Reebonz — long‑standing SG luxury marketplace (brand/assets have gone through changes and a live‑selling pivot; functionality and availability have shifted — check the current app/website before buying). (vulcanpost.com)

Tips

• Authentication: for second‑hand purchases prefer platforms with an authentication process (Vestiaire, The Luxury Closet, formal “certified” programmes on Carousell/Zalora). (apps.apple.com)
• Shipping & duties: check each app’s delivery and customs policy for Singapore before checkout — international retailers differ in shipping speed and import/duty handling. (Apps list SG shipping options in their store pages.) (apps.apple.com)

If you’d like, I can:

• show which of these have iOS/Android apps and provide direct App Store / Play Store names, or
• filter by category (e.g., handbags only), price range, or new vs pre‑owned.
