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.

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 Cage 27-28" 29-30" 31-32" 33-34" 35-36" 37-38" 39-41" 42-43" 44-45"
Band Size (USA) 32 34 36 38 40 42 44 46 48
UK 32 34 36 38 40 42 44 46 48
Europe 70 75 80 85 90 - - - -
France 85 90 95 100 105 - - - -
Italy 1 2 3 4 5 - - - -
Australia 10 12 14 16 18 - - - -
  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:
Bust Minus Band 0" 1" 2" 3" 4" 5" 6" 7" 8"
Cup Size (USA) AA A B C D DD/E DDD/F G H
Europe AA A B C D E F G H
France AA A B C D E F G H
Italy - A B C D DD E F FF
Australia - A B C D DD E F FF

How To Care For Your Bra

Ideally, hand wash your lingerie

As an alternative to hand washing, Wacoal recommends the following:

  • Machine wash a bra inside of a mesh lingerie wash bag.
  • Fold the cups together, fasten the hooks and eyes, and place the straps and hooks and eyes inside of the cups.
  • Place the bra in the bag and into the washer.
  • Use mild detergent, no additives or bleach.
  • Remove from wash bag and dry hanging or flat.

Never place any lingerie in the dryer.

The rule of thumb is that a bra should be washed after every time it is worn to remove body oils, perfumes, moisturizers, self tanners, etc. A bra should be retired after being worn and washed 100 times as it will not offer as much support as needed.


  • Always wash bras and panties before you wear them for the first time.
  • Measure your bra size every year.
  • Replace your bras every 6 months due to wear from laundering and use.
