Unlike years gone by, there is now a vast array of bra sizes and styles available to suit every taste and every figure. This is great news for those amongst us that are petite or larger than average. It is also great news for those that like to combine the practical benefits of a good bra with style, comfort and a dash of sexiness.
Measure Band Size
Measure around your rib cage, just under the bust. Make sure you pull the measuring tape tight and horizontally around your body. Round to the nearest whole inch.
If you come up with an even number, add 2. If you come up with an odd number, add 3. The result is your band size
Measure Cup Size
Measure around your back, across the fullest part of your breast. Make sure the measuring tape is horizontal but not too tight. Round to the nearest whole inch.
Subtract this number from your band size. The difference corresponds to your cup size. See the chart below for your cup size
Calculate your bra size:
Subtract your band measurement (step 1) from your cup measurement (step 2). Generally, for each inch in difference, the cup goes up by one size.See the cup size conversion chart here.
Example:
Step 1: 34″ under measurement +4″ = 38″ band
Step 2: 40″ over measurement
Step 3: 40″ – 38″ = 2″ or Cup “B”
Your size would be 38B
