Pro Tip:- Science behind right bra size
1. How do I know my bra size accurately?
Use a soft tape:
Band size: Measure snugly under your bust (in inches or cm).
Cup size: Measure around the fullest part of your bust.
2. Why do sizes vary by country?
Different regions use unique sizing standards. Our calculator auto-adjusts (e.g., a US 34C ≠ UK 34C).
3. What if my size seems incorrect?
Double-check measurements! If issues persist, try our fit guide or consult a professional fitter.
4. What’s the difference between US, UK, and EU bra sizes?
Sizing systems vary by region (e.g., a US 34C = UK 34C = EU 75C). Our Measurement Calculator automatically converts sizes for you.
5. Why does my bra size change over time?
Weight fluctuations, pregnancy, and aging affect breast tissue. Recheck your size every 6–12 months using our Bra Measurement Calculator for the best fit.
6. How tight should a bra band be?
It should fit snugly on the loosest hook (you can fit two fingers underneath). If it rides up, use our Bra Measurement Calculator to reassess.
7. How do I know my cup size?
Subtract your band size from your bust measurement (e.g., 1” = A cup, 2” = B cup). Our Measurement Calculator does the math for you!
8. How often should I replace my bras?
Every 6–12 months (or when elastic stretches out). Use our Bra Measurement Calculator before buying new ones.
9. Is a 34B the same as a 32C?
No! A 32C has a smaller band but larger cup volume than a 34B. Try our Calculator to compare sister sizes.
