Bra size kivabe mapbo? (How do I measure my bra size at home?)

You need two measurements in inches: the underbust (wrap a measuring tape tightly around your ribcage, just below the bust, and exhale) and the overbust (measure loosely around the fullest part of your bust). Enter both numbers into the calculator above to get your band and cup size instantly.

What is the +4/5 method for bra sizing?

The +4/5 method is the traditional sizing standard used for most imported lingerie in Bangladesh. If your underbust measurement is an even number (e.g., 30 inches), add 4 inches to get your band size (34). If it is an odd number (e.g., 29 inches), add 5 inches (34). The difference between your overbust and band size determines your cup: 1 inch = A, 2 inches = B, 3 inches = C, 4 inches = D, and so on.

32B mane ki? (What does a bra size like 32B mean?)

The number (32) is the band size — the measurement around your ribcage under the bust. The letter (B) is the cup size — the difference between your bust and band measurements. So a 32B means a 32-inch band with a B cup (about a 2-inch difference between bust and band).

What is a sister size?

Sister sizes are bra sizes with the same cup volume but different band sizes. If you go down one band size, go up one cup size (and vice versa). For example, 34B, 32C, and 36A all hold the same cup volume. If your exact size is out of stock, your sister size is the best alternative.

Why does my calculated size feel wrong?

The most common errors are measuring over thick clothes or a padded bra, not pulling the tape tight enough on the underbust (making the band size too big), or pulling too tight on the overbust (making the cup too small). Calculators are about 90% accurate — if the result feels off, re-measure on bare skin or contact Sassy Secret BD on WhatsApp for free size help.

Which bra size is most common in Bangladesh?

The most commonly purchased sizes in Bangladesh are 32B, 34B, and 36B. However, research suggests around 80% of women wear the wrong size, so it is worth measuring rather than guessing based on what you usually buy.

US / UK Size	Asian / CN Tag	EU Size

⚠️ Band numbers are identical across Asian, CN, and EU (all use cm). Cup letters AA–D are the same; US/UK DD = CN/Asian E.
📏 Fit tip: Asian-brand cups often run ~1 size smaller in volume. If your size is 75C, try 75D when ordering from a Chinese brand.

⚠️ Common Measurement Errors:
• If you measured over clothes (T-shirt/Bra), the size might be wrong.
• If you didn't pull the tape tight on the Underbust, the Band size will be too big.

If your Underbust is Odd (e.g., 29), we add 5 inches.
The difference between your Band and Bust determines your Cup (A, B, C, D, etc.).
