Do you mean “biggest” by brand value, by annual sales (revenue), or by cultural/influence in luxury fashion? Below are three short, up‑to‑date ways to look at the biggest fashion labels, with the date/source for each ranking.

1. By brand value (top brands globally — FashionUnited’s 2024 index)

• Louis Vuitton, Nike, Chanel, Hermès, Gucci, Zara, Adidas, Uniqlo, Dior, Cartier.

2. By annual revenue / size of parent companies (major global groups, 2024)

• LVMH (group) — €84.7 billion revenue in 2024 (owner of Louis Vuitton, Dior, Fendi, etc.). (LVMH.com)
• Nike — ~$51.4 billion revenue (fiscal 2024). (investors.Nike.com)
• Inditex (Zara) — largest apparel retailer by sales (approx. $/€39B range, FY2023). (www-statista-com.ezproxy.canberra.edu.au)

3. By current luxury‑market prominence / influence (common top luxury houses, 2024–2025 coverage)

• Louis Vuitton, Chanel, Hermès, Gucci, Dior, Prada, Saint Laurent, Bottega Veneta, Fendi, Burberry. (Rankings and indexes such as Vogue Business / VisualCapitalist note these consistently in the top tier across 2024–2025). (voguebusiness.com, visualcapitalist.com)

Notes:

• “Biggest” depends on the metric: brand value (marketing/brand strength), revenue (sales size), market cap/profitability, or cultural influence (trend leadership). The lists above use those three common measures and are current as reported in 2024–early 2025. (fashionunited.com, LVMH.com, visualcapitalist.com)

If you want a single ranked top 20 by one specific metric (brand value, revenue, market cap, or a curated “most influential” list), tell me which metric and I’ll give a detailed top‑20 with figures and sources.
