Calculate Now →🟣 The 5 Mistakes That Ruin 90% of International Orders
- Thinking EU “E” cup = UK “E” cup → Nope. EU E is usually UK F or FF.
- Ordering Shein in “US” sizing → They don’t use it. Ever.
- Forgetting France adds +10 to +15 cm to the band.
- Freaking out when Japan tells you you’re an F or G → That’s normal for a US DD!
- Ignoring your breast shape → A projected girl in a shallow Etam bra will cry. A shallow girl in a deep Wacoal will swim.
🟣 Quick-Reference Lines Everyone Saves
- US 34DD → UK 34E → EU 90E/F → Japan/Korea 75F (sometimes G) → Shein 75F or 80E
- US 32D → UK 32D → EU 85E → Japan/Korea 70F → Shein 70E
- US 36C → UK 36C → EU 95C → Japan/Korea 80D → Shein 80C/D

🟣 Final Pro Tips From Someone Who’s Returned Way Too Many Bras
- Always read the last 20 reviews that mention “runs small,” “deep cups,” or “narrow wires.”
- When in doubt, choose the bigger cup (you can tighten a band with an extender; you can’t add cup volume).
- Shop return-friendly sites first: Shein, ASOS, Zalando, Amazon Prime Wardrobe, Next.
- Bookmark this page — sizing charts shift every season, and I’ll keep this updated.
