Yes — Zalora is a legitimate, well‑established online fashion retailer that operates in Singapore (Zalora.sg).

Why you can trust it

• It’s a major regional e‑commerce brand used by many shoppers across Southeast Asia.
• The site uses standard secure checkout (HTTPS) and accepts mainstream payment methods.
• It provides order confirmations, tracking, and a published returns/refunds policy.

A few practical notes (shopping safely)

• Confirm you’re on the official domain (zalora.sg) and that the URL shows the padlock (HTTPS).
• Check whether the item is sold by “Zalora” or a third‑party seller on their platform and read the product reviews.
• Use a credit card or other payment methods with buyer protection when possible.
• Keep order confirmations/screenshots and check the returns/refund policy and time limits.
• If you have an unresolved consumer problem in Singapore, you can escalate to the Consumers Association of Singapore (CASE) or your bank for a chargeback.
