How to choose the right bra?

An estimated 70% of women do not know their proper bra measurements. Without knowing these measurements, it can be very difficult to buy fashionable and well fitting clothes. Many women's clothing items use bra or cup size measurements to distinguish differences in fit, so these measurements can be extremely important. This section will arm you with the knowledge you need for these crucial measurements.

Additionally, a woman's breasts change significantly over time, particularly during and after pregnancy. Weight loss, gain and monthly cycle variations can also have an effect on the fit of your bra. It is advised that you check your bra size once or twice a year or as necessary due to significant weight changes.

Determining your Bra/Band size
(ribcage circumference measurement)

1. Measure around the chest directly under the breast at a constant height with the cloth measuring tape. Add 5 inches to that measurement. This dimension is your bra/band size (If the bra size works out to an ODD number go up one inch to the next EVEN number.) This should equal the circumference around the chest, directly above the breasts/under the arms.

2. Now measure around the chest at the height of the fullest part of the breast. The measuring tape should be held horizontal, flat on your back, and your arms should be down. Make a note of that measurement (only used for comparison) and compare it to the Bra Size from step 1.
Determining your Cup size
(projection of breasts from chest wall)

3. To determine the proper Cup Size, find the difference between step 2 and step 1 (step 2 - step 1.) Use the chart below to determine your Cup Size.

Difference & cup size
Half inch - AA
One inch - A
Two inches - B
Three inches - C
Four inches - D
Five inches - DD or E
Six inches - F
Seven inches - G

Note: 1 inch ~= 2.5 centimeters

Example:
Step 1: Underbust measurement is 37". Add 5 inches. Bra Size is 42.
Step 2: Full bust measurement is 45".
Step 3: 45 - 42 = 3" difference. Cup size is C.
Result: Buy a 42C bra.
