According to Wacoal, 8 out of 10 women are in the wrong size bra. A bra should make you feel beautiful as well as enhance your wardrobe. A properly fitting bra should contain, support, lift, and shape your bust, as well as be comfortable.

A Good Bra Fit
  • Breast tissue is completely contained in the cups.
  • Absolutely no gaps or wrinkles in the cups or any spilling over of breast tissue.
  • Center section between the cups should lie flat on the chest.
  • Wires lay flat against the chest wall and wrap around and do not touch breast tissue.
  • Band of the bra must anchor low at or below shoulder blades.
  • You should be able to run 2 fingers under the band without any shifting of the garment.
  • With side view, bra/breast should sit in the middle to upper half of arm between elbow and shoulder.
  • Bra should remain anchored and not shift when raising arms above head or sitting in a chair.
  • The bra must feel comfortable.

    Signs A Bra Does Not Fit
    • Bra is uncomfortable.
    • Straps fall off shoulders.
    • Underwires poke or bother.
    • Back of bra rides up.
    • Breasts bulge or spill out of the top or sides of the bra.

    How To Measure Your Bra Size

    Determine Band Size

    1. Wear a good-fitting, non-padded bra and face the mirror.
    2. Wrap the measuring tape very snugly around your rib cage, just under your bustline. Make sure the tape is even and parallel with the floor.
    3. Exhale and pull the measuring tape as tightly as possible. This is your Rib Cage measurement.
    4. If the measurement is odd, add 5". If the measurement is even, add 4". If the measurement is 40" or above, add only 3-4 inches. This is your Band Size.
    5. Use this chart as a guideline.
    6. Select the Band Size according to your Rib Cage measurement as follows:
    Rib Cage27-28"29-30"31-32"33-34"35-36"37-38"39-41"42-43"44-45"
    Band Size (USA)323436384042444648

    1. To confirm the Band Size, wrap the measuring tape loosely around your rib cage, just above your bustline and under your arms. This measurement should equal the Band Size.

    Determine Cup Size

    1. Wear a good-fitting, non-padded bra.
    2. Wrap the measuring tape around the fullest part of your bust, making sure the tape is parallel to the floor and lying flat around your body.
    3. This will be a loose measurement. You should be able to easily insert 2 fingers sideways between the side of your breast and the tape. This is your Bust Measurement.
    4. The difference in inches between the Band Size and the Bust Measurement will determine the cup size:
