Short answer: Yes — Zalora is a legitimate, well‑known online fashion retailer operating in Singapore (it’s part of the Global Fashion Group and runs the Zalora.sg site). (Zalora.sg)

A bit more detail and what to watch for:

• Legitimacy/background: Zalora Singapore is an established e‑commerce business (Zalora Group / Global Fashion Group) with thousands of brand listings and an official Singapore site. (Zalora.sg)
• Customer experience: many shoppers buy from Zalora and report satisfactory deliveries and returns, but public review sites show a mix of positive and negative experiences — common complaints include slow or problematic returns, occasional delivery issues, and inconsistent item quality. Reviews on Trustpilot and consumer complaint sites reflect that mixed experience. (trustpilot.com)
• Risk assessment: scam‑watch tools and domain validators rate Zalora.sg as low‑to‑medium risk (i.e., not a scam), but they also recommend usual online‑shopping caution. (scam-detector.com)

Practical tips if you decide to shop:

• Buy directly from Zalora.sg (not from suspicious third‑party sellers or links). (Zalora.sg)
• Check seller/brand listing (branded stores on Zalora are more likely to be authentic).
• Read recent reviews for the specific item/brand and look at seller ratings. (trustpilot.com)
• Use a secure payment method (card or payment provider with buyer protection).
• Keep order and delivery records, and photograph items on arrival if you expect to return them (some disputes turn on condition/packaging).
• Review Zalora’s returns/refund policy before purchase and note any deadlines (Zalora typically offers return windows but terms can vary by item). (Zalora.sg)

Bottom line: Zalora.sg is a legitimate retailer in Singapore, but like many large marketplaces it gets mixed customer feedback — exercise normal online‑shopping precautions. (Zalora.sg)
