Frequently Asked Questions
Is Shein trustworthy for UK orders?
Shein operates a legitimate e-commerce platform and processes millions of UK orders. Delivery times are longer than ASOS or Zara (7–12 days standard) because most items ship from China. The 35-day return window is the most generous of the platforms compared here. Photo reviews from verified purchasers on product pages significantly help with assessing accurate fit and colour before ordering.
Which platform has the best returns process?
ASOS has the simplest returns process — a QR code return label on the app, drop off at a post office or parcel locker. Zara's in-store return is the most convenient for shoppers near a store (instant, no waiting). Shein requires initiating a return through the app and printing a return label; the process is slightly more involved but the 35-day window is the longest.
Which is best if I need something delivered quickly?
ASOS unambiguously wins on speed — next-day delivery until 10pm Monday–Friday, with Premier membership covering unlimited deliveries for around £15 per year. Boohoo and Zara click-and-collect are close alternatives. Shein is not suitable for urgent purchases due to the 7–12 day standard delivery window.
