Great — here are reliable places and ways to shop for environmentally friendly fashion in Singapore, grouped so you can jump to what you prefer (multi‑brand eco stores, preloved/thrift, pop‑ups & concept shops, and repair/mending options).

Multi‑brand eco / sustainable stores (good for new sustainable labels)

• The Green Collective — a permanent multi‑brand eco store & online marketplace carrying local and APAC sustainable fashion, accessories and lifestyle products. (greenisthenewblack.com)
• Something Sustainable (multi‑brand pop‑up space in Tanjong Pagar) — hosts rotating eco brands and local makers. (something-sustainable.com)
• Sui (slow‑fashion label with a flagship store in Duxton) — an example of a Singapore slow‑fashion brand with a physical store so you can check materials and construction in person. (sg.wearesui.com)

Preloved, thrift and recommerce (best for reducing demand for new production)

• Queensway Shopping Centre and Lucky Plaza — long‑standing hubs for thrift and second‑hand shops in Singapore (many small thrift stores and bargains). (zula.sg)
• Specialist thrift/resale shops and pop‑ups: The Barn @ Katong, LPB Thrift, Function Five, The Fashion Pulpit, Two Worlds — good for curated preloved/consignment finds. (scmp.com)
• Recommerce marketplaces: Refash (omni‑channel resale platform with physical stores in SG/MY) and Carousell — excellent for buying/selling preloved pieces. (en.wikipedia.org)

Concept stores, boutiques & where to find sustainable global labels

• Concept pop‑ups and small boutiques along Haji Lane, Keong Saik / Duxton Hill and Tanglin Mall often stock ethical or eco brands (and brands like VEJA are sold at local boutiques and department stores). Check local listings before you go. (thepeakmagazine.com.sg)

Repair, mending & skills (to extend garment life)

• Mending workshops and community repair events (Fashion Revolution SG “Mending with Mates”, Movin’ Menders / ZERRIN workshops) — great ways to learn visible mending and get clothes repaired rather than discarded. Many community events are run regularly. (eventbrite.sg)
• Brand repair programs: some local sustainable labels offer repairs (example: Esse and other slow labels may offer repair support or kits) — check brand policies before buying. (essethelabel.com)

Quick shopping tips to make purchases truly sustainable

• Buy preloved or higher‑quality timeless pieces; prefer natural or recycled fibers (organic cotton, Tencel/Lyocell, linen, recycled polyester) and transparent brands that show materials and factory info. (greenisthenewblack.com)
• Ask about origins and certifications, inspect construction, and favour repairable items. Attend local pop‑ups or concept stores where you can meet makers and ask questions directly. (greenisthenewblack.com)

If you’d like, I can:

• Pull together a short walking route (addresses and opening hours) in a neighbourhood you’ll be visiting (e.g., Orchard/Tanglin, Haji Lane/Duxton Hill, or Queensway/Katong), or
• Find current pop‑ups, second‑hand events or the next mending workshop on specific dates.
