Quick answer
Replica shirt? Buy your normal size. Authentic shirt? Size up one.
If you remember nothing else from this page, remember that. Replica shirts (the £75 ones with a loose fit) fit normally. Authentic / player versions (the £110+ ones cut for athletes) fit a full size smaller than every casual T-shirt you already own.
Replica vs Authentic — what's the difference?
Replica (fan)
The £75 option
- • Thicker, more forgiving polyester
- • Loose, comfortable fit
- • Stitched-on badge (most cases)
- • Full range of sizes: XS to 3XL
- • Fits like a normal T-shirt — buy your usual size
Authentic (player)
The £110+ option
- • Lightweight performance fabric (Vaporknit / Heat.rdy)
- • Slim, athletic cut
- • Heat-sealed badge
- • Usually XS to 2XL only
- Size up one — medium players wear large authentic shirts

Buying on Amazon — pro tips
- 1. Check the seller. If the seller is “Amazon EU” or the official brand store (Nike, Adidas, Puma), you're getting genuine product with easy returns. Third-party sellers with no reviews are the riskiest.
- 2. Always read the size chart on the listing. Manufacturer charts vary between cycles. The size chart in the listing itself is the authoritative one.
- 3. Check the fit tag. “Regular fit” means replica. “Slim fit”, “Authentic”, “Vaporknit”, “Heat.rdy” or “Player version” all mean authentic — size up.
- 4. Use Prime for free returns. If you're not sure about the size, order two sizes and return one. Amazon Prime members get free returns on most kit purchases.
- 5. Buy early. Popular sizes of the top-selling teams (England, Brazil, Argentina) sell out 4–6 weeks before kick-off. Don't leave it to matchday one.
