Finding the right bra size can feel like solving a mystery—but it doesn’t have to be! If you’re a medium bra size (typically around 34B to 36C), you’re in one of the most common size ranges. Yet, many women still struggle with fit issues like slipping straps, tight bands, or spillage.

This guide will help you:
✅ Understand what a medium bra size really means
✅ Measure yourself accurately at home
✅ Choose the best styles for support and comfort
✅ Avoid common bra shopping mistakes

Let’s dive in!

What Is a Medium Bra Size?

A medium bra size usually refers to:

• Band sizes: 34 to 36 (the measurement around your ribcage)

• Cup sizes: B to C (but can vary based on band size)

Example sizes considered "medium":

• 34B

• 34C

• 36B

• 36C

Note: Sizing varies by brand—always check their size chart!

How to Measure Your Bra Size at Home

Step 1: Measure your band size

• Wrap a soft measuring tape snugly around your ribcage (just under your bust).

• Round to the nearest even number (e.g., 33" → 34 band).

Step 2: Measure your bust size

• Measure around the fullest part of your bust (keep the tape loose).

Step 3: Calculate your cup size

• Subtract your band size from your bust size.

  • 1-inch difference = A cup

  • 2-inch = B cup

  • 3-inch = C cup (and so on).

Example: If your band is 34" and bust is 36", you’d be a 34B.

Best Bra Styles for Medium Sizes

Not all bras are created equal! Here are the top styles for medium sizes:

✔ T-Shirt Bras – Seamless, smooth cups perfect for everyday wear.
✔ Balconette Bras – Lifts and enhances shape with wider-set straps.
✔ Sports Bras – Medium-impact styles (like 34C sports bras) for workouts.
✔ Wireless Bras – Super comfy for all-day wear without digging in.

5 Common Bra Mistakes (And How to Fix Them!)

1. Wearing the wrong band size → If it rides up, go down a band size (e.g., 36B → 34C).

2. Ignoring cup spillage → Try a larger cup (34C → 34D).

3. Choosing style over support – A pretty bra that doesn’t fit well is pointless!

4. Not adjusting straps – They should stay put without digging in.

5. Wearing an old bra – Replace bras every 6-12 months (stretched-out bands don’t support well).

How to Care for Your Bras (So They Last Longer!)

• Wash in a mesh bag (never in the regular wash cycle!).

• Use mild detergent – Harsh soaps break down elastic.

• Air dry flat – Heat from dryers ruins fabric and wires.

• Rotate bras – Wearing the same one daily wears it out faster.

Final Thoughts

A well-fitting bra boosts comfort, posture, and confidence—so don’t settle for “almost right.” If you’re a medium bra size, double-check your measurements and try different styles to find your perfect match.
