Because wearing the right bra size changes everything.
Finding your correct bra size shouldn’t feel confusing, embarrassing, or impossible. Most women are actually wearing the wrong size without even realizing it — which can lead to back pain, shoulder marks, spillage, uncomfortable wires, and bras that simply don’t fit the way they should.
At Her Hawen, we believe lingerie should feel like confidence, not discomfort. So here’s a simple step-by-step guide to measuring your bra size at home — no fancy tools, no awkward fitting rooms.
⸻
What You’ll Need
* A soft measuring tape
* A mirror
* A non-padded bra (or measure without one)
* 5 minutes
⸻
Step 1: Measure Your Band Size
Your band size is the measurement around your ribcage, directly under your bust.
How to do it:
* Wrap the measuring tape snugly around your ribcage.
* Keep it straight and parallel to the floor.
* Exhale normally before checking the number.
* Don’t pull too tight — it should feel firm, not uncomfortable.
Example:
If your underbust measurement is:
* 27–28 inches → Band size 32
* 29–30 inches → Band size 34
* 31–32 inches → Band size 36
Your band size is usually an even number.
⸻
Step 2: Measure Your Bust Size
Now measure around the fullest part of your bust.
How to do it:
* Stand straight with relaxed shoulders.
* Wrap the tape around the fullest part of your chest.
* Keep the tape comfortably loose — don’t flatten your bust.
* Make sure the tape sits evenly all around.

Step 3: Calculate Your Cup Size
The difference between your bust measurement and band measurement determines your cup size.
Cup Size Chart
Difference (inches) Cup Size
1 inch A
2 inches B
3 inches C
4 inches D
5 inches DD/E
6 inches DDD/F
Example:
* Underbust: 30 inches → Band size 34
* Bust: 37 inches
* Difference: 3 inches
Your size = 34C

Signs You’re Wearing the Wrong Bra Size
You might need a different size if:
* Your straps keep falling
* Your band rides up your back
* There’s spillage from the cups
* The cups gape or wrinkle
* Your underwire digs into your skin
* You constantly adjust your bra throughout the day
A bra should feel supportive, secure, and almost unnoticeable.
⸻
Sister Sizes Matter Too
Bra sizing isn’t always exact across every brand. That’s where sister sizing helps.
For example:
* 32C → sister sizes are 34B and 30D
* 34D → sister sizes are 36C and 32DD
This helps if:
* The band feels too tight
* The cups fit but overall comfort feels off
* You’re between sizes

Common Mistakes Women Make While Measuring
Measuring Over Padded Bras
Padded bras can change your bust measurement and lead to inaccurate sizing.
Pulling the Tape Too Tight
A too-tight measurement usually results in uncomfortable bras.
Ignoring Band Fit
Your band provides most of the support — not the straps.
Assuming Your Size Never Changes
Your bra size can change due to:
* Weight fluctuations
* Hormonal changes
* Workouts
* Stress
* Age
* Period cycles
⸻
The Truth About Bra Sizes
A “bigger” cup size doesn’t mean a bigger bust overall.
For example:
* 32D and 38D are completely different volumes.
* Cup size changes relative to the band size.
That’s why the letter alone doesn’t define your size.

Her Hawen Tip
The best bra isn’t the tightest one.
It’s the one you forget you’re wearing.
Comfort, support, confidence, softness, and fit should exist together — and that’s exactly what we design for at Her Hawen.
Because lingerie should fit your body, not force your body to fit into it.

Final Thoughts
Learning your correct bra size is one of the simplest ways to feel more comfortable in your clothes and more confident in your body.
And remember:
Your size is just a measurement — not a definition.
Bodies change. Sizes change. Comfort matters most.
