Size Guide- How to Choose Your Blessie Bra Size

How to Measure

Step 1: Measure Overbust (Full Bust)
Lean forward slightly (about 45°) and measure around the fullest part of your bust.

Step 2: Measure Underbust (Band Size)
Stand upright and measure snugly around your ribcage under the bust.

Step 3: Find Your Cup Size
Overbust – Underbust = Bust Difference (cm)
Example, if your under bust is 75 cm and your upper bust is 85 cm:

  • Difference = 85 – 75 = 10 cm

  • 10 cm falls within 9–12 cm (B Cup)
    ✅ Recommended size = 75/34 → M
