How To Measure Your Bra Size

Wearing the right bra size can change everything — from how you look to how confident and comfortable you feel throughout the day. At Love & Secret, we believe every woman in Malaysia deserves a bra that fits like a second skin — especially when it comes to wireless bras.

Here’s a step-by-step guide to help you measure your bra size accurately from the comfort of your home.


Step 1: Measure Your Band Size 下胸围

Using a soft measuring tape, measure around your rib cage, just below your bust. Make sure the tape is snug but not tight.

📌 Tip: Breathe normally and keep the tape level all around your body.

Record this number in centimeters — this is your underbust measurement (e.g. 73cm).


Step 2: Measure Your Bust Size 胸围

Next, measure around the fullest part of your bust — usually over the nipples.

📌 Keep the tape comfortably loose — you don’t want to squish the bust.

✅ This is your bust measurement (e.g. 85cm).


Step 3: Find Your Band Size

Use the chart below to find your band size based on your underbust measurement:

Band SizeUnderbust (cm)
32 (70)68–72 cm
34 (75)73–77 cm
36 (80)78–82 cm
38 (85)83–87 cm
40 (90)88–92 cm
42 (95)93–97 cm
44 (100)98–102 cm

📌 Example: If your underbust is 73 cm, your band size is 34 (75).


Step 4: Calculate Your Cup Size

Now subtract your band size from your bust size:

📌 Bust – Band = Cup Size

Use the result to determine your cup size:

Difference (cm)Cup Size
<10 cmA
11–13 cmB
14–16 cmC
16–19 cmD
19–21 cmE
21–24 cmF
24–27 cmG

Example:

  • Bust = 85 cm
  • Band = 73 cm
  • Difference = 12 cm → Cup Size = B
  • Final Bra Size = 34B (75B)

Why It Matters

Wearing the wrong size can cause:

  • Discomfort or pain
  • Poor posture
  • Red marks or skin irritation

A correct-fitting wireless bra gives you freedom of movement, all-day comfort, and natural shape — especially in hot Malaysian weather.
