The how-to for a perfect fit
Step 1: Measure Your Band Size
Put on a non-padded bra and stand in front of a mirror. Wrap a measuring tape snugly around your ribcage, just below your bust. Keep the tape level and flat against your body. Take the reading after a relaxed exhale. If the number is odd, round up to the next even number (e.g., 33" → 34").
Step 2: Measure Your Bust Size
Wrap the measuring tape around the fullest part of your bust. Keep the tape level - snug but not tight. Breathe naturally and take the reading in a relaxed state. Do not pull the tape taut or hold your breath.
Step 3: Calculate Your Cup Size
Cup Size = Bust Measurement − Band Measurement
