A great looking outfit starts with proper foundation underneath the clothes. Yet, according to the Swiss lingerie company Triumph International, up to 60 per cent of women wear bras that do not fit well. Poorly fitting bras do not properly support the bust, leading to tension and pain in the neck, shoulders, and back, as well as unsightly bulges and gaps in clothing. Knowing how to measure your bra size ensures that you buy bras that fit so you avoid these problems.
Measure the band width
Measure the diametre of the chest at the narrowest point just under the bust. Remove all clothing from the upper body, including a bra. Stand straight with relaxed shoulders, and wrap a flexible tape measure around the torso below the bottom of the breasts, pulling the tape measure as tight as possible.
This step identifies the length of the band that wraps around the body and holds the bra in place. When the band is too loose, it does not provide the support breasts need. A band that is too tight digs into the skin, pinches the rib cage, and distorts posture.
Measure the cups
Wrap a tape measure around the fullest part of the breasts while wearing a non-padded bra to find the cup size. Rest the tape measure loosely around the torso. It should not be higher in the front or back.
Cup size designates how much space the breasts need to rest comfortably in the cups. When the cups are too big, the breasts spill over the top; too small and they move around too much within the bra. Both can leave bulges and gaps in shirts that make clothing look sloppy.
Determine the bra size
The bra size is a combination of the band width and cup size. Standard bra sizes vary in different regions of the world. In Australia, bra sizes have a number that corresponds to the length of the band and a letter that represents the cup size.
- 65 cm under bust width = 8
- 70 cm under bust width = 10
- 75 cm under bust width = 12
- 80 cm under bust width = 14
- 85 cm under bust width = 16
- 90 cm under bust width = 18
- 95 cm under bust width = 20
- 100 cm under bust width = 22
- 105 cm under bust width = 24
Cup sizes follow a similar pattern. A woman with a 13 cm difference between her band width and cup measurements needs an A cup bra, while a woman with a 15 cm difference needs a B cup bra. This pattern continues as follows:
- 17 cm difference between band and cup = C cup
- 19 cm difference between band and cup = D cup
- 21 cm difference between band and cup = DD cup
- 23 cm difference between band and cup = E cup
- 25 cm difference between band and cup = F cup
- 27 cm difference between band and cup = G cup
Tips for obtaining accurate measurements
Enlisting the help of a trusted friend usually yields better results than trying to measure one's own body. It is impossible to keep the arms still and maintain posture while juggling the tape measure. Even a slight shift in posture skews the measurements, resulting in bands or cups that are too large or too small.
Women's bodies change through weight fluctuations and the aging process. As a result, their bra sizes change over time. For best results, women need to take new bra measurements at least once each year and after gaining or losing weight.
Keep in mind that bra sizes differ between styles and manufacturers. For example, a demi bra offers less coverage than a full size bra, and this changes the way the bra fits and looks under clothes. In addition, manufacturers often use different measurements when determining bra sizes, so a 14C bra made by one company is sometimes smaller or larger than the same size from another company.
How to buy bras on eBay
Buying a new bra is easy on eBay. Sellers on the site offer a selection of traditional and sports bras from popular manufacturers around the world. To find these items, enter key terms in the search bar on any eBay page, and refine the results by adding details like the bra size, manufacturer, style, or colour you prefer. As you review the listings, read each description carefully, and communicate directly with the seller to ensure that you know exactly what he or she offers so that you receive the product you have in mind.
