The Ultimate Guide:

Feeling uncomfortable in your bra? You’re not alone. A staggering 80% of women are estimated to be wearing the wrong bra size! But what if we told you that finding your perfect fit could be done in the comfort of your own home, with just a tape measure and a few simple steps?

Getting your measurements right is the foundation of comfort and confidence. Let’s ditch the guesswork and find your true size!

Step 1: Measure Your Band Size (The Underbust)

Your band provides about 80% of your bra’s support, so getting this right is crucial.

1. Preparation: Stand upright, wearing only your thinnest, non-padded bra (or no bra at all).
2. Position: Wrap a soft tape measure snugly around your rib cage directly underneath your bust. Make sure the tape is level all the way around your back.
3. Read: Exhale completely to get the smallest possible measurement. Note this number.
4. Calculate:
   • If your measurement is an even number, add 4 inches. This is your band size.
   • If your measurement is an odd number, add 5 inches. This is your band size.

• Example: If you measure 30 inches, your band size is 30 + 4 = 34.
• Example: If you measure 31 inches, your band size is 31 + 5 = 36.

Step 2: Measure Your Bust Size (The Fullest Part)

This measurement determines your cup size.

1. Preparation: Keep your tape measure ready.
2. Position: Wrap the tape measure loosely around the fullest part of your bust. Ensure the tape is still level across your back and not digging into your breast tissue.
3. Read: Note this number.

• Example: If your fullest bust measurement is 39 inches.

Step 3: Calculate Your Cup Size

Now, for the magic! Your cup size is determined by the difference between your bust measurement and your calculated band size.

Cup Size = Full Bust Measurement – Band Size

Each inch of difference corresponds to a specific cup letter:

Difference (Inches)	Cup Size
Less than 1 inch	AA
1 inch	A
2 inches	B
3 inches	C
4 inches	D
5 inches	DD/E
6 inches	DDD/F
7 inches	G
8 inches	H
9 inches	I
10 inches	J

• Example: If your calculated band size was 34 and your full bust was 39 inches:
  • 39 (Bust) – 34 (Band) = 5 inches.
  • According to the chart, 5 inches = DD/E cup.
  • Your estimated bra size is 34DD/E.

Final Check: The Fit Test!

Even with perfect measurements, try-on is essential. When you try on a bra in your newly calculated size:

• Band: It should be snug on the loosest hook, level across your back, and allow only two fingers to slide underneath.
• Cups: Your breast tissue should be fully enclosed, with no spilling over the top or sides (no “quadri-boob”) and no gaping at the top or bottom.
• Gore: The center panel (gore) between the cups should lie completely flat against your sternum.
• Straps: They should be adjusted to be supportive but not digging into your shoulders. The straps are for minor adjustments, not primary support!

Remember, bra sizing can vary slightly between brands, so use these measurements as your starting point. You’re now equipped with the knowledge to find bras that truly fit, support, and flatter your unique shape!
