GRAB A MEASURING TAPE!
• UNDERBUST
Wrap the measuring tape around your body—over your rib cage and just below your bust.
• SHAPERTIP: Was your measurement an odd number or at a half-inch mark? Round down to the nearest even number.
• FULL BUST
Wrap the measuring tape around your body and over the fullest part of your bust. And be sure you’re not pulling the tape away from the front of your bust for the most accurate measurement.
• SHAPERTIP: Did your measurement fall on a half-inch mark? Round up.
