Here are well-regarded online stores & marketplaces in Singapore where you can reliably find organic clothing (organic cotton, bamboo, linen, certified pieces) — with a short note on what each is best for:

• The Green Collective (online + physical store) — curated multi‑brand marketplace focused on certified/eco-conscious apparel (lots of organic-cotton basics and children’s wear). Good for variety and vetted sustainability claims. (thegreencollective.sg)

• Zerrin — Singapore boutique/marketplace that curates slow‑fashion and sustainable labels (useful filters for natural/organic materials). Good for independent designers and responsibly made pieces. (timeout.com)

• Earthkind (Earthkind.co) — curated sustainable & ethical lifestyle marketplace in Singapore that often stocks organic textile brands and small-batch labels. Good for conscious shoppers wanting transparency. (brandradar.org)

• Zhai Eco (Zhai) — local brand/retailer offering garments in bamboo, linen and other natural fibres suited to Singapore’s climate (some ranges marketed as organic/natural). Good for breathable, tropical-friendly materials. (herworld.com)

• Nimisski — Singapore womenswear label/retailer positioning itself as eco-conscious with sustainable collections; useful if you want locally designed organic or low‑impact pieces. (Nimisski.com)

• International organic-focused labels available to Singapore shoppers — Organic by John Patrick, Honest By, Chinti & Parker and similar brands sell organic-cotton collections and ship/are stocked by local boutiques and marketplaces. Good when you want certified organic basics or premium organic knits. (herworld.com)

Tips to choose:

• Look for explicit material and certifications (GOTS, OCS) on product pages.
• Check product care and composition — “organic” should be accompanied by % (e.g., 100% organic cotton).
• Prefer marketplaces that vet brands (The Green Collective, Zerrin, Earthkind) if you want less risk of greenwashing.
