Accurate measurement is key to finding the right fit. Here's a simple guide: 1. Band Size: Measure around the ribcage, just under the bust. Add 4 inches to this measurement if it's even, or 5 inches if it's odd, to get the band size. 2. Cup Size: Measure around the fullest part of the bust. Subtract the band size from this measurement. Each inch difference corresponds to a cup size (e.g., 1 inch = A cup, 2 inches = B cup).
