Notes on rankings and data

• Different rankings use different metrics (site visits, e‑commerce net sales, market cap, regional strength). For example, eCommerceDB and Statista list Shein as the leading global fashion e‑commerce site by sales/visits in recent years, while NRF’s Top Retailers list highlights large multi‑category retailers (Walmart, Amazon) that also sell massive apparel volumes.

If you want:

• A ranked top 10 by a specific metric (global sales, monthly visits, or U.S. popularity) I can produce that with the latest published figures.
• Recommendations for where to shop by price range, style, or country/region.
