Most women are wearing the wrong bra size. Studies suggest up to 80% of women have never measured themselves correctly. The result? Straps that dig in, cups that overflow, bands that ride up, and days that feel more uncomfortable than they should.
Getting your bra size right changes everything. A well-fitted sexy bra does not just look better. It feels better. It gives you the lift and support your body deserves. Here is how to measure at home in three simple steps.
What You Need
A soft measuring tape. That is it. Stand in front of a mirror in a non-padded bra or no bra. Stand straight, breathe normally. Measurements taken slouched or with a padded bra will be inaccurate.
Step 1: Measure Your Band Size (Underbust)
Wrap the measuring tape snugly around your ribcage, just below your bust. Keep it level and flat against your skin. Do not pull it tight or let it sag.
Round the number to the nearest whole number.
• If the number is even, add 4 inches.
• If the number is odd, add 5 inches.
The result is your band size.
Example: You measure 29 inches. 29 is odd, so 29 + 5 = 34. Your band size is 34.
Step 2: Measure Your Bust Size (Overbust)
Wrap the tape around the fullest part of your bust, usually across the nipples. Keep the tape parallel to the ground. It should be snug but not pressed in. Round to the nearest whole number.
Step 3: Calculate Your Cup Size
Subtract your band size from your bust measurement. The difference tells you your cup size.
• 1 inch difference = Cup A
• 2 inches = Cup B
• 3 inches = Cup C
• 4 inches = Cup D
• 5 inches = Cup DD or E
Example: Bust = 37 inches, Band = 34 inches. Difference = 3. Your size is 34C.

How to Know Your Bra Actually Fits
Measuring is only half of it. Here is how a correctly fitted bra should feel and look:
The Band
It should sit level across your back, not ride up. You should be able to slide two fingers underneath it comfortably. Start on the loosest hook so you have room to tighten as the band stretches over time.
The Cups
Your breasts should sit fully inside the cups with no spillage at the top or sides. There should be no gaping or wrinkling. If the cup creases, you need a smaller cup. If your breast tissue spills over, go up a cup.
The Straps
They should stay in place without digging into your shoulders. If you are constantly adjusting them, the band is doing the wrong job. The band should carry 80% of the support, not the straps.
The Centre Gore
That small section of fabric between the cups should lie flat against your sternum. If it floats away from your body, try a larger cup size.
Common Mistakes to Avoid
• Measuring over a padded bra. It throws off the bust measurement.
• Rounding down. If your measurement is 33.5, round up to 34, not down to 33.
• Pulling the tape too tight. Snug is correct. Tight compresses the tissue and reads smaller.
• Wearing the wrong bra during measurement. Non-padded or no bra is best.
What About Sexy Lingerie? Does Size Change?
For everyday bras, your standard bra size is a reliable guide. For sexy lingerie like bralettes, garter sets, or babydoll dresses, sizing works differently. Most pieces on Pratiharye list measurements in the product description. Use your underbust and overbust measurements directly for the best fit.
Pratiharye carries inclusive sizes from 38 to 48, so you will find sexy lingerie that fits your actual body, not a sample size.
When to Re-Measure
Bra size is not fixed. Re-measure every 6 to 12 months, or after significant weight changes, pregnancy, breastfeeding, or surgery. Hormonal changes can also affect size throughout the month, so if you feel different, re-measure.
Frequently Asked Questions
Q1. How often should I measure my bra size?
Every 6 to 12 months, or after any significant change in weight, pregnancy, or surgery. Your size can shift even without obvious physical changes.
Q2. My band size is even but the formula says to add 4. What if it already feels right?
The formula is a starting point, not a rule. If your underbust measurement is exactly on a standard band size and feels comfortable, you may not need to add anything. Always try the bra on and assess the fit above everything else.
Q3. What is a sister size?
A sister size has the same cup volume but a different band. For example, 34C and 36B have the same cup volume. If your size is unavailable, try the sister size by going one band size up and one cup size down, or vice versa.
Q4. Why does my sexy bra fit differently than my everyday bra in the same size?
Sexy lingerie like bralettes, mesh bras, or lace sets are often made without underwire or structured cups. They run differently than regular bras. Always check the specific size chart for each piece.
Q5. Can I measure without a tape measure?
You can use a piece of string and then measure it against a ruler. It is less accurate but works in a pinch. A proper soft measuring tape is always the better option.
Q6. What if I am between sizes?
Always round up, not down. A slightly larger band with a smaller cup can sometimes work too. Try sister sizes to find the most comfortable fit.
Q7. Does sexy lingerie from Pratiharye come in plus sizes?
Yes. Pratiharye offers plus-size lingerie in sizes 38 to 48. Many pieces in the bridal, babydoll, and garter collections are available in these sizes with the same quality and design as standard sizes.
