Step 1. Under Bust / Band Size Measurement:

• Always use a soft measuring tape
• Without wearing a bra, measure your rib cage where your bra band would sit
• Ensure the tape is firm and straight
• This measurement is your Under Bust measurement

Step 2. Over Bust / Cup Size Measurement:

• Measure either wearing a non-padded bra or no bra
• Measure the fullest part of your bust with the tape positioned around your back at your band level (where the bottom of the bra band sits)
• Do not hold the tape too tight as this will flatten the measurement
• This measurement is your Over Bust or cup size measurement
