Finding the right bra size starts with two simple measurements. Follow this quick guide to discover the fit that feels supportive, comfortable, and made for your body.
Step 1 — Measure Your Band Size
Wrap a soft measuring tape snugly around your ribcage, directly under your bust.
• Keep the tape level all the way around • Measure firmly, but not too tight • Round to the nearest whole number
👉 This number determines your band size.
Example:
If your underbust measurement is 34 inches, your band size is likely 34.
Step 2 — Measure Your Bust Size
Measure around the fullest part of your bust while keeping the tape comfortably relaxed.
• Do not pull the tape too tightly • Keep your arms relaxed at your sides • Wear a non-padded bra for the most accurate result
👉 This number helps determine your cup size.
Step 3 — Find Your Cup Size
Subtract your band measurement from your bust measurement.
